+It's an example for LZMA + x86 Filter use.

+Lzma86_Encode
+-------------
+level - compression level: 0 <= level <= 9, the default value for "level" is 5.
+
+
+dictSize - The dictionary size in bytes. The maximum value is
+        128 MB = (1 << 27) bytes for 32-bit version
+          1 GB = (1 << 30) bytes for 64-bit version
+     The default value is 16 MB = (1 << 24) bytes, for level = 5.
+     It's recommended to use the dictionary that is larger than 4 KB and
+     that can be calculated as (1 << N) or (3 << N) sizes.
+     For better compression ratio dictSize must be >= inSize.
+
+filterMode:
+    SZ_FILTER_NO   - no Filter
+    SZ_FILTER_YES  - x86 Filter
+    SZ_FILTER_AUTO - it tries both alternatives to select best.
+              Encoder will use 2 or 3 passes:
+              2 passes when FILTER_NO provides better compression.
+              3 passes when FILTER_YES provides better compression.
+
+Lzma86Encode allocates Data with MyAlloc functions.
+RAM Requirements for compressing:
+  RamSize = dictionarySize * 11.5 + 6MB + FilterBlockSize
+      filterMode     FilterBlockSize
+     SZ_FILTER_NO         0
+     SZ_FILTER_YES      inSize
+     SZ_FILTER_AUTO     inSize

+  SZ_OK               - OK
+  SZ_ERROR_MEM        - Memory allocation error

+    - Some bugs were fixed
+
+  - man pages added (thank Mohammed Adnene Trojette)
+  - bug #1112167 fixed (Temporary directory must be on same partition as target)
+    p7zip failed moving the temporary file at the end of
+    compressing to target file if the directories don't reside
+    on the same partition (or network path).
+  - bug #1164659 fixed (Invalid file date for "big endian" machine)
+  - p7zip now uses ".so" instead of ".dll"
+  - p7zip now handles "ctrl-c" and "kill" to cleanup temporary files before exiting

+  
+
+Version 4.14.01
+===============
+  - huge speed up for multi CPUs machines (Thanks to loderunner - http://sourceforge.net/users/loderunner/).
+  - some code cleanup
+  - Fix problems with link files or directories.
+  - "7z a dummy -tgzip -so Doc.txt > archive.gz" now works.
+  - in the messages, the path separator is now '/' instead of '\'.
+
+Version 4.14
+============
+
+  - From Windows version of 7-zip 4.14 :
+    - STL using was reduced
+    - 7za now supports Split(001) archives
+    - "7za | more" now works
+    - Bugs item #1093095 : Usage banner now says "7za" (instead of "7z") when the binary is "7za"
+
+  - use of AString instead of std::string (no more need of #include <string>")
+  - makefile.linux_gcc_2.95_no_need_for_libstdc added to build 7za for the
+    p7zip*_bin.tar.bz2 package.
+    7za provided by p7zip*_bin.tar.bz2 is build on Debian 3.0 with gcc 2.95.4
+    and should now find the locale on all kinds of Linux (Debian, Fedora, Mandrake, ...).
+
+Version 4.13
+============
+  - new port of 7za from the source of 7za 4.13Beta for Windows
+
+  - From Windows version of 7-zip 4.13 :
+    - Switch "--" stops switches parsing
+    - Some bugs were fixed
+    - User's manual updated (DOCS/MANUAL/index.htm)
+
+  - makefile.netbsd_x86 added [Bug #1069055].
+
+  - new method to install 7z and its plugins (the "link" method do no work)
+
+  - installer added (install.sh).
+
+  - makefile.macosx_with_fink becomes makefile.macosx
+    and makefile.macosx uses c++ instead of CC
+    (on some MacOSX, CC is a link to gcc instead of g++)
+
+  - new flag "-utf16" to enable "utf16" conversion [Bug #1075229].
+
+  - new logic to automatically enable or disable "utf16" conversion :
+    no locale, locale=="C" or locale=="POSIX" implies utf16=off
+    else  utf16=on
+    uses "-utf16" or "-no-utf16" to change this behaviour.
+    [Bug #1075229]
+
+  - 7z (compiled with -O2) works now on Sparc Solaris. 
+
+Version 4.12
+============
+  - new port of 7za from the source of 7za 4.12Beta for Windows
+
+  - From Windows version of 7-zip 4.11 and 4.12 :
+    - 7-Zip now supports Zip64 extension of ZIP format. So now it's 
+      possible to compress files bigger than 4 GB to ZIP archives.
+    - Some bugs were fixed
+
+  - fix "7za a archive.7z file" that added all the files and directories
+    with filename "file", "FILE", "File" ...
+
+  - p7zip now displays the locale (ex : en_US.UTF-8) in the banner.

+    CAUTION : use this flag when you do not plan to export your archive.
+
+  - support creation of self extracting archive.
+
+  - better support of symbolic link (now, an invalid symbolic link
+    do not stop archiving but displays a warning).
+
+  - better support of files that the user cannot read.
+    (now this kind of file is not added to the archive, and p7zip displays a warning).
+
+  - return of 7z and its plugins.
+
+  - support of listing/testing/extracting files from a splitted archive (only with 7z).
+
+  - support of MacOX X 10.X.
+
+  - creation of Gzip/Tar archives didn't work on Linux Alpha.
+
+  - see "contrib/VirtualFileSystemForMidnightCommander/readme" to use 7za with "mc".
+
+Version 4.10
+============
+  - new port of 7za from the source of 7za 4.10Beta for Windows
+    => p7zip now work on big endian CPU.
+
+  - 7z for Unix is not maintain anymore (because as the source of unrar plugin for 7z

+    In Windows/Time.h add "#include <time.h>"
+    and prototype change for FileTimeToUnixTime()
+
+  - bug 990684 Corrected : support of filesystem
+    that support case sensitive filenames.
+    Example, since version 0.91 : 
+    "7z a glibc -r glibc-2.3.2"
+    does not terminate with error :
+      Duplicate filename:
+      glibc-2.3.2\sysdeps\m88k\m88100\add_n.S
+      glibc-2.3.2\sysdeps\m88k\m88100\add_n.s 
+
+Version 0.90
+============
+  - build of 7z.exe and its DLL.
+  7z.exe support more archive formats than 7za.exe
+  thanks to DLL in Formats and Codecs directories
+  - "#pragma once" is now in comments

+7z ANSI-C Decoder 4.62
+----------------------
+
+7z ANSI-C provides 7z/LZMA decoding.
+7z ANSI-C version is simplified version ported from C++ code.
+
+LZMA is default and general compression method of 7z format
+in 7-Zip compression program (www.7-zip.org). LZMA provides high 
+compression ratio and very fast decompression.
+
+
+LICENSE
+-------
+
+7z ANSI-C Decoder is part of the LZMA SDK.
+LZMA SDK is written and placed in the public domain by Igor Pavlov.
+
+Files
+---------------------
+
+7zDecode.*   - Low level 7z decoding
+7zExtract.*  - High level 7z decoding
+7zHeader.*   - .7z format constants
+7zIn.*       - .7z archive opening
+7zItem.*     - .7z structures
+7zMain.c     - Test application
+
+
+How To Use
+----------
+
+You must download 7-Zip program from www.7-zip.org.
+
+You can create .7z archive with 7z.exe or 7za.exe:
+
+  7za.exe a archive.7z *.htm -r -mx -m0fb=255
+
+If you have big number of files in archive, and you need fast extracting, 
+you can use partly-solid archives:
+  
+  7za.exe a archive.7z *.htm -ms=512K -r -mx -m0fb=255 -m0d=512K
+
+In that example 7-Zip will use 512KB solid blocks. So it needs to decompress only 
+512KB for extracting one file from such archive.
+
+
+Limitations of current version of 7z ANSI-C Decoder
+---------------------------------------------------
+
+ - It reads only "FileName", "Size", "LastWriteTime" and "CRC" information for each file in archive.
+ - It supports only LZMA and Copy (no compression) methods with BCJ or BCJ2 filters.
+ - It converts original UTF-16 Unicode file names to UTF-8 Unicode file names.
+ 
+These limitations will be fixed in future versions.
+
+
+Using 7z ANSI-C Decoder Test application:
+-----------------------------------------
+
+Usage: 7zDec <command> <archive_name>
+
+<Command>:
+  e: Extract files from archive
+  l: List contents of archive
+  t: Test integrity of archive
+
+Example: 
+
+  7zDec l archive.7z
+
+lists contents of archive.7z
+
+  7zDec e archive.7z
+
+extracts files from archive.7z to current folder.
+
+
+How to use .7z Decoder
+----------------------
+
+Memory allocation
+~~~~~~~~~~~~~~~~~
+
+7z Decoder uses two memory pools:
+1) Temporary pool
+2) Main pool
+Such scheme can allow you to avoid fragmentation of allocated blocks.
+
+
+Steps for using 7z decoder
+--------------------------
+
+Use code at 7zMain.c as example.
+
+1) Declare variables:
+  inStream                 /* implements ILookInStream interface */
+  CSzArEx db;              /* 7z archive database structure */
+  ISzAlloc allocImp;       /* memory functions for main pool */
+  ISzAlloc allocTempImp;   /* memory functions for temporary pool */
+
+2) call CrcGenerateTable(); function to initialize CRC structures.
+
+3) call SzArEx_Init(&db); function to initialize db structures.
+
+4) call SzArEx_Open(&db, inStream, &allocMain, &allocTemp) to open archive
+
+This function opens archive "inStream" and reads headers to "db".
+All items in "db" will be allocated with "allocMain" functions.
+SzArEx_Open function allocates and frees temporary structures by "allocTemp" functions.
+
+5) List items or Extract items
+
+  Listing code:
+  ~~~~~~~~~~~~~
+    {
+      UInt32 i;
+      for (i = 0; i < db.db.NumFiles; i++)
+      {
+        CFileItem *f = db.db.Files + i;
+        printf("%10d  %s\n", (int)f->Size, f->Name);
+      }
+    }
+
+  Extracting code:
+  ~~~~~~~~~~~~~~~~
+
+  SZ_RESULT SzAr_Extract(
+    CArchiveDatabaseEx *db,
+    ILookInStream *inStream, 
+    UInt32 fileIndex,         /* index of file */
+    UInt32 *blockIndex,       /* index of solid block */
+    Byte **outBuffer,         /* pointer to pointer to output buffer (allocated with allocMain) */
+    size_t *outBufferSize,    /* buffer size for output buffer */
+    size_t *offset,           /* offset of stream for required file in *outBuffer */
+    size_t *outSizeProcessed, /* size of file in *outBuffer */
+    ISzAlloc *allocMain,
+    ISzAlloc *allocTemp);
+
+  If you need to decompress more than one file, you can send these values from previous call:
+    blockIndex, 
+    outBuffer, 
+    outBufferSize,
+  You can consider "outBuffer" as cache of solid block. If your archive is solid, 
+  it will increase decompression speed.
+
+  After decompressing you must free "outBuffer":
+  allocImp.Free(outBuffer);
+
+6) call SzArEx_Free(&db, allocImp.Free) to free allocated items in "db".
+
+
+
+
+Memory requirements for .7z decoding 
+------------------------------------
+
+Memory usage for Archive opening:
+  - Temporary pool:
+     - Memory for uncompressed .7z headers
+     - some other temporary blocks
+  - Main pool:
+     - Memory for database: 
+       Estimated size of one file structures in solid archive:
+         - Size (4 or 8 Bytes)
+         - CRC32 (4 bytes)
+         - LastWriteTime (8 bytes)
+         - Some file information (4 bytes)
+         - File Name (variable length) + pointer + allocation structures
+
+Memory usage for archive Decompressing:
+  - Temporary pool:
+     - Memory for LZMA decompressing structures
+  - Main pool:
+     - Memory for decompressed solid block
+     - Memory for temprorary buffers, if BCJ2 fileter is used. Usually these 
+       temprorary buffers can be about 15% of solid block size. 
+  
+
+7z Decoder doesn't allocate memory for compressed blocks. 
+Instead of this, you must allocate buffer with desired 
+size before calling 7z Decoder. Use 7zMain.c as example.
+
+
+Defines
+-------
+
+_SZ_ALLOC_DEBUG   - define it if you want to debug alloc/free operations to stderr.

+
+<P>Measures speed of the CPU and checks RAM for errors.</P>

+b [number_of_iterations] [-mmt{N}] [-md{N}] [-mm={Method}]
+</PRE>
+
+<P>There are two tests:<P>
+<OL>
+  <LI>Compressing with LZMA method
+  <LI>Decompressing with LZMA method
+</OL>
+
+<P>The benchmark shows a rating in MIPS (million instructions per second).
+The rating value is calculated from the measured CPU speed and it
+is normalized with results of Intel Core 2 CPU with multi-threading option 
+switched off. So if you have Intel Core 2 Duo, 
+rating values must be close to real CPU frequency.</P>
+
+<P>You can change the upper dictionary size to increase memory usage by -md{N} switch.
+Also, you can change the number of threads by -mmt{N} switch.</P>
+
+<P>The <B>Dict</B> column shows dictionary size. For example, 21 means 2^21 = 2 MB.</P>
+
+<P>The <B>Usage</B> column shows the percentage of time the processor is working.
+It's normalized for a one-thread load. For example, 180% CPU Usage for 2 threads
+can mean that average CPU usage is about 90% for each thread.</P>
+
+<P>The <B>R / U</B> column shows the rating normalized for 100% of CPU usage.
+That column shows the performance of one average CPU thread.</P>
+
+<P><B>Avr</B> shows averages for different dictionary sizes.</P>
+<P><B>Tot</B> shows averages of the compression and decompression ratings.</P>
+
+<P>Compression speed and rating strongly depend on memory (RAM) latency.
+
+<P>Decompression speed and rating strongly depend on the integer performance of the CPU.
+For example, the Intel Pentium 4 has big branch
+misprediction penalty (which is an effect of its long pipeline) and pretty slow
+multiply and shift operations. So, the Pentium 4 has pretty low decompressing ratings.</P>
+
+<P>You can run a CRC calculation benchmark by specifying -mm=crc.
+That test shows the speed of CRC calculation in MB/s. The first column shows the size of the block.
+The next column shows the speed of CRC calculation for one thread. The other columns are results
+for multi-threaded CRC calculation.</P> 
+
+
+<H4>Examples</H4>
+
+<PRE class="example">
+7z b
+</PRE>
+runs benchmarking.
+
+<PRE class="example">
+7z b -mmt1 -md26
+</PRE>
+runs benchmarking with one thread and 64 MB dictionary.
+
+<PRE class="example">
+7z b 30
+</PRE>
+<P>runs benchmarking with default settings for 30 iterations.</P>

+
+<P>Large Pages mode increases the speed of compression.
+However, there is a pause at the start of compression while 7-Zip allocates the large pages in memory.
+If 7-Zip can't allocate large pages, it allocates usual small pages.
+Also, the Windows Task Manager doesn't show the real memory usage of the program, if 7-Zip uses large pages.
+This feature works only on Windows 2003 / XP x64. 
+Also, it requires administrator's rights for your system.
+The recommended size of RAM for this feature is 1 GB or more.
+To install this feature, you must run the 7-Zip File Manager at least once, 
+close it, and then reboot the system.</P>
+<P>Your system can hang for several seconds at compressing starting, if you use -slp mode.
+So it's not recommended to use -slp mode to compress small data sets (less than 100 MB).</P>

+All SFX modules are uncompressed. You can use UPX program 
+(http://upx.sourceforge.net) 
+to compresss such modules. After compressing by the UPX program, the size of the
+sfx module will be reduced to 40-50% of its original size.
+</P>
+
+<H4>SFX modules for installers</H4>
+<P>SFX modules for installers are included in an external package (7z_extra). You can download
+these modules from www.7-zip.org. SFX modules for installers (7zS.sfx and 7zSD.sfx)
+allow you to create your own installation program.
+Such a module extracts the archive to the user's temp folder, and runs a specified program,
+and removes the temp files after the program finishes.
+A self-extracting archive for installers must be created as joining 3 files:
+SFX_Module, Installer_Config, 7z_Archive. 
+In addition, an optional file, Installer_Config, is allowed. You can use the following command to
+create an installer self-extracting archive:</P>
+<PRE class="example">
+copy /b 7zS.sfx + config.txt + archive.7z archive.exe
+</PRE>
+
+<P>An optimally small installation package size can be achieved,
+if the installation files are uncompressed before including them in the 7z archive.</P>
+
+<P><SPAN class="filename">-y</SPAN> switch for installer module specifies quiet mode extraction.</P>
+
+<H4>Installer Config file format</H4>
+<P>
+This config file contains commands for the Installer. The file begins with the string
+<B>;!@Install@!UTF-8!</B> and ends with <B>;!@InstallEnd@!</B>.
+The file must be written in UTF-8 encoding.
+The file contains any or all these string pairs:

+<P>You may omit any pair.</P>
+
+<P>There are two ways to run a installation program: <B>RunProgram</B> and <B>ExecuteFile</B>.
+Use <B>RunProgram</B>, if you want to run a program from the .7z archive.
+Use <B>ExecuteFile</B>, if you want to open a document from the .7z archive, or
+if you want to execute a command from Windows.</P>
+
+<P>If you use <B>RunProgram</B>, and if you specify empty directory prefix: <B>Directory</B>="",

+
+<P>If you don't specify a
+<A class="parameter" href="#new_archive_name"><I>!{new_archive_name}</I></A> option, then
+all options will refer to the main archive (the archive assigned on the command line after the 7z command).
+If you specify <A class="parameter" href="#new_archive_name"><I>!{new_archive_name}</I></A>
+option, then 7-Zip also will create a new archive with the specified name and all options
+will refer to that new archive.</P>
+
+<P>Multiple update switches are supported.
+7-Zip can create any number of new archives during one operation.</P>
+
+<P>By default, the action set for each new archive is assigned
+as the action set of the main command. There are 3 different
+action sets for commands: <A href="../commands/add.htm">a (Add)</A>,
+  <A href="../commands/delete.htm">d (Delete)</A>,
+  <A href="../commands/update.htm">u (Update)</A>.
+You can overload any &lt;state_action> pair.</P>
+
+<H4>Time zone notes</H4>
+<P>If you change time zone (when you move your computer to another time zone 
+or if there are clock changes for daylight saving in your zone), you can have some problems 
+with update commands that depend from file's modification time. It's strongly recommended to use only 
+file system that uses Coordinated Universal Time (UTC) and archive format that also uses UTC. 
+In that case you will have no problems with time zone changes.
+Also it's recommended to use only UTC formats in other cases, for example, if you send files to 
+someone in another time zone.</P>
+
+<P>Also in some cases there are no problems, if both file system and archive format use local time, for example, FAT file system and ZIP format.</P> 
+<UL>
+<LI>UTC file systems: NTFS
+<LI>UTC archive formats: .zip with -mtc switch, 7z, tar, gzip2, iso, wim
+<LI>Local time file systems : FAT, FAT32
+<LI>Local time archive formats : rar, zip, cab
+</UL>
+
+<H4>Examples</H4>
+
+<PRE class="example">

+7-Zip method IDs (9.18)
+-----------------------
+
+Each compression or crypto method in 7z has unique binary value (ID).
+The length of ID in bytes is arbitrary but it can not exceed 63 bits (8 bytes).
+
+If you want to add some new ID, you have two ways:
+1) Write request for allocating IDs to 7-zip developers.
+2) Generate 8-bytes ID:
+
+    3F ZZ ZZ ZZ ZZ ZZ MM MM 
+
+    3F              - Prefix for random IDs (1 byte)
+    ZZ ZZ ZZ ZZ ZZ  - Developer ID (5 bytes). Use real random bytes. 
+                      
+    MM MM           - Method ID (2 bytes)
+
+    You can notify 7-Zip developers about your Developer ID / Method ID.
+
+    Note: Use new ID only if old codec can not decode data encoded with new version.
+
+
+List of defined IDs
+-------------------
+      
+00 - Copy
+
+03 - Delta

+      GNU LESSER GENERAL PUBLIC LICENSE
+           Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+          Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+      GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+          NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+         END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the

+Sources history of the 7-Zip
+----------------------------
+
+9.18           2010-11-02
+-------------------------	
+- New small SFX module for installers (C/Util/SfxSetup).
+
+
+9.17           2010-10-04
+-------------------------
+- IStream.h::IOutStream::
+    STDMETHOD(SetSize)(Int64 newSize) PURE;
+  was changed to
+    STDMETHOD(SetSize)(UInt64 newSize) PURE;
+
+
+9.09           2009-12-12
+-------------------------
+- The bug was fixed:
+   Utf16_To_Utf8 funstions in UTFConvert.cpp and 7zMain.c
+   incorrectly converted surrogate characters (the code >= 0x10000) to UTF-8.
+
+
+9.05           2009-07-05
+-------------------------
+- FileMapping.h::CFileMapping now returns WRes
+
+
+9.04           2009-05-30
+-------------------------
+- ICoder.h: NCoderPropID::EEnum values were changed
+
+
+9.02           2009-04-23
+-------------------------
+- Bug was fixed: if swap2 filter was requests at compression,
+  7-zip used swap4 filter instead (but id was swap2), so archives were incorrect.
+  
+4.61           2008-11-23
+-------------------------
+- Bug in ver. 4.58+ was fixed:
+   7-Zip didn't use any -m* switch after -mtc, -mcl or -mcu for .zip archives. 
+- Bug in .CAB code was fixed. 7-Zip didn't show some empty files,
+  if .CAB archive contains more than one empty file.
+   
+
+4.59           2008-07-27
+-------------------------
+- Bug was fixed:
+   LZMA Encoder in fast compression mode could access memory outside of 
+   allocated range in some rare cases.
+   
+
+4.59 alpha     2008-05-30
+-------------------------
+- BUGS was fixed: 
+    7zOut.cpp: 7-Zip incorrectly wrote size of property records in some cases.
+    7zIn.cpp:  7-Zip incorrectly work with archive, containg archive properties.
+
+4.58 alpha 9   2008-04-29
+-------------------------
+- BUG was fixed: 7-Zip showed incorrect timestamps in ISO files.
+
+
+4.58 alpha 8   2008-04-15
+-------------------------
+- BUG in 4.58 alpha 5/6/7 was fixed:
+    LZMA encoder worked incorrectly, if lp != 0.
+- Unicode (UTF-8) support for filenames in .ZIP archives. Now there are 3 modes:
+    1) Default mode: 7-Zip uses UTF-8, if the local code page doesn't contain required symbols.
+    2) -mcu switch:  7-Zip uses UTF-8, if there are non-ASCII symbols.
+    3) -mcl switch:  7-Zip uses local code page.
+- Now it's possible to use -mSW- and -mSW+ switches instead of -mSW=off and -mSW=on  
+
+
+4.58 alpha 7   2008-04-08
+-------------------------
+- BUG was fixed: BZip2Encoder and BZip2Decoder used CEvent objects without 
+  creating, when BZip2 code was called with one thread (with -mmt1 switch or with 
+  default switches on single thread CPU).
+- .lzma support.
+- RPM and NSIS support was improved.
+- LZMA now stores only (2 << n) or (3 << n) dictionary size value to LZMA properties.
+
+
+4.58 alpha 6   2008-03-27
+-------------------------
+- NTFS time extra in ZIP.
+- New item property - kpidTimeType - VT_UI4 (0 - NTFS, 1 - Unix, 2 - DOS).
+- Static CRC table is not required now for Lzma Encoder (in Lz MatchFinder).
+
+
+4.58 alpha 5   2008-03-19
+-------------------------
+- Creation time (-mtc switch) for .7z archives
+- LZMA encoder was converted to ANSI-C
+
+
+4.58 alpha 3   2008-02-25
+-------------------------
+- Speed optimizations for LZMA decoding. Now it uses C code instead of C++.
+- 7-Zip now has 128 MB dictionary limit for 32-bit version:
+  It's for speed optimization: kNumLogBits = 9 + sizeof(size_t) / 2;
+- TAR: 'D' link flag support.
+- 7-Zip now can unpack multivolume RAR archives created with 
+  "old style volume names" scheme (-vn switch) and names *.001, *.002, ...
+- Fixed bugs:
+  - 7-Zip FM could not copy / move files to root network folders like \\COMPNAME\FOLDERNAME\
+    In case of move it removed original files.
+  - SFX-WIN: if there are errors, it still could return 0.
+  - ZIP (.XPS file) isZip64 && thisDiskNumber16 == 0xFFFF.
+  - ZIP name updating:
+      If zip file contains extra field and you try to change properties of files,
+      7-zip tries to delete all extra fileds (except for WzAES).
+      And that code could hang.
+  -  7-Zip GUI didn't suggest BZip2 dictionary size used in previous run.
+  -  If creation time stamp was included in .RAR archive, 7-zip used creation time stamp 
+     as modification time stamp.
+
+4.58 alpha 2   2007-12-31
+-------------------------
+- Small changes in Deflate and LZMA compression.
+- Some speed optimizations.
+
+
+4.57

+LZMA SDK 9.20
+-------------
+
+LZMA SDK provides the documentation, samples, header files, libraries, 
+and tools you need to develop applications that use LZMA compression.
+
+LZMA is default and general compression method of 7z format
+in 7-Zip compression program (www.7-zip.org). LZMA provides high 
+compression ratio and very fast decompression.
+
+LZMA is an improved version of famous LZ77 compression algorithm. 
+It was improved in way of maximum increasing of compression ratio,
+keeping high decompression speed and low memory requirements for 
+decompressing.
+
+
+
+LICENSE
+-------
+
+LZMA SDK is written and placed in the public domain by Igor Pavlov.
+
+Some code in LZMA SDK is based on public domain code from another developers:
+  1) PPMd var.H (2001): Dmitry Shkarin
+  2) SHA-256: Wei Dai (Crypto++ library)
+
+
+LZMA SDK Contents
+-----------------
+
+LZMA SDK includes:
+
+  - ANSI-C/C++/C#/Java source code for LZMA compressing and decompressing
+  - Compiled file->file LZMA compressing/decompressing program for Windows system
+
+
+UNIX/Linux version 
+------------------
+To compile C++ version of file->file LZMA encoding, go to directory
+CPP/7zip/Bundles/LzmaCon
+and call make to recompile it:
+  make -f makefile.gcc clean all
+
+In some UNIX/Linux versions you must compile LZMA with static libraries.
+To compile with static libraries, you can use 
+LIB = -lm -static

+LZMA features
+-------------
+  - Variable dictionary size (up to 1 GB)
+  - Estimated compressing speed: about 2 MB/s on 2 GHz CPU
+  - Estimated decompressing speed: 
+      - 20-30 MB/s on 2 GHz Core 2 or AMD Athlon 64
+      - 1-2 MB/s on 200 MHz ARM, MIPS, PowerPC or other simple RISC
+  - Small memory requirements for decompressing (16 KB + DictionarySize)
+  - Small code size for decompressing: 5-8 KB
+
+LZMA decoder uses only integer operations and can be 
+implemented in any modern 32-bit CPU (or on 16-bit CPU with some conditions).
+
+Some critical operations that affect the speed of LZMA decompression:
+  1) 32*16 bit integer multiply
+  2) Misspredicted branches (penalty mostly depends from pipeline length)
+  3) 32-bit shift and arithmetic operations
+
+The speed of LZMA decompressing mostly depends from CPU speed.
+Memory speed has no big meaning. But if your CPU has small data cache, 
+overall weight of memory speed will slightly increase.
+
+
+How To Use
+----------
+
+Using LZMA encoder/decoder executable
+--------------------------------------
+
+Usage:  LZMA <e|d> inputFile outputFile [<switches>...]
+
+  e: encode file
+
+  d: decode file
+
+  b: Benchmark. There are two tests: compressing and decompressing 
+     with LZMA method. Benchmark shows rating in MIPS (million 
+     instructions per second). Rating value is calculated from 
+     measured speed and it is normalized with Intel's Core 2 results.
+     Also Benchmark checks possible hardware errors (RAM 
+     errors in most cases). Benchmark uses these settings:
+     (-a1, -d21, -fb32, -mfbt4). You can change only -d parameter. 
+     Also you can change the number of iterations. Example for 30 iterations:
+       LZMA b 30
+     Default number of iterations is 10.
+
+<Switches>
+  
+
+  -a{N}:  set compression mode 0 = fast, 1 = normal
+          default: 1 (normal)
+
+  d{N}:   Sets Dictionary size - [0, 30], default: 23 (8MB)
+          The maximum value for dictionary size is 1 GB = 2^30 bytes.
+          Dictionary size is calculated as DictionarySize = 2^N bytes. 
+          For decompressing file compressed by LZMA method with dictionary 
+          size D = 2^N you need about D bytes of memory (RAM).
+
+  -fb{N}: set number of fast bytes - [5, 273], default: 128
+          Usually big number gives a little bit better compression ratio 
+          and slower compression process.
+
+  -lc{N}: set number of literal context bits - [0, 8], default: 3
+          Sometimes lc=4 gives gain for big files.
+
+  -lp{N}: set number of literal pos bits - [0, 4], default: 0
+          lp switch is intended for periodical data when period is 
+          equal 2^N. For example, for 32-bit (4 bytes) 
+          periodical data you can use lp=2. Often it's better to set lc0, 
+          if you change lp switch.
+
+  -pb{N}: set number of pos bits - [0, 4], default: 2
+          pb switch is intended for periodical data 
+          when period is equal 2^N.
+
+  -mf{MF_ID}: set Match Finder. Default: bt4. 
+              Algorithms from hc* group doesn't provide good compression 
+              ratio, but they often works pretty fast in combination with 
+              fast mode (-a0).
+
+              Memory requirements depend from dictionary size 
+              (parameter "d" in table below). 
+
+               MF_ID     Memory                   Description
+
+                bt2    d *  9.5 + 4MB  Binary Tree with 2 bytes hashing.
+                bt3    d * 11.5 + 4MB  Binary Tree with 3 bytes hashing.
+                bt4    d * 11.5 + 4MB  Binary Tree with 4 bytes hashing.
+                hc4    d *  7.5 + 4MB  Hash Chain with 4 bytes hashing.
+
+  -eos:   write End Of Stream marker. By default LZMA doesn't write 
+          eos marker, since LZMA decoder knows uncompressed size 
+          stored in .lzma file header.
+
+  -si:    Read data from stdin (it will write End Of Stream marker).
+  -so:    Write data to stdout
+
+
+Examples:
+
+1) LZMA e file.bin file.lzma -d16 -lc0 
+
+compresses file.bin to file.lzma with 64 KB dictionary (2^16=64K)  
+and 0 literal context bits. -lc0 allows to reduce memory requirements 
+for decompression.
+
+
+2) LZMA e file.bin file.lzma -lc0 -lp2
+
+compresses file.bin to file.lzma with settings suitable 
+for 32-bit periodical data (for example, ARM or MIPS code).
+
+3) LZMA d file.lzma file.bin
+
+decompresses file.lzma to file.bin.
+
+
+Compression ratio hints
+-----------------------
+
+Recommendations
+---------------
+
+To increase the compression ratio for LZMA compressing it's desirable 
+to have aligned data (if it's possible) and also it's desirable to locate
+data in such order, where code is grouped in one place and data is 
+grouped in other place (it's better than such mixing: code, data, code,
+data, ...).
+
+
+Filters
+-------
+You can increase the compression ratio for some data types, using
+special filters before compressing. For example, it's possible to 
+increase the compression ratio on 5-10% for code for those CPU ISAs: 
+x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.
+
+You can find C source code of such filters in C/Bra*.* files
+
+You can check the compression ratio gain of these filters with such 
+7-Zip commands (example for ARM code):
+No filter:
+  7z a a1.7z a.bin -m0=lzma
+
+With filter for little-endian ARM code:
+  7z a a2.7z a.bin -m0=arm -m1=lzma        
+
+It works in such manner:
+Compressing    = Filter_encoding + LZMA_encoding
+Decompressing  = LZMA_decoding + Filter_decoding
+
+Compressing and decompressing speed of such filters is very high,
+so it will not increase decompressing time too much.
+Moreover, it reduces decompression time for LZMA_decoding, 
+since compression ratio with filtering is higher.
+
+These filters convert CALL (calling procedure) instructions 
+from relative offsets to absolute addresses, so such data becomes more 
+compressible.
+
+For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.
+
+

+
+ANSI-C LZMA Decoder
+~~~~~~~~~~~~~~~~~~~
+
+Please note that interfaces for ANSI-C code were changed in LZMA SDK 4.58.
+If you want to use old interfaces you can download previous version of LZMA SDK
+from sourceforge.net site.
+
+To use ANSI-C LZMA Decoder you need the following files:
+1) LzmaDec.h + LzmaDec.c + Types.h
+LzmaUtil/LzmaUtil.c is example application that uses these files.
+
+
+Memory requirements for LZMA decoding
+-------------------------------------
+
+Stack usage of LZMA decoding function for local variables is not 
+larger than 200-400 bytes.
+
+LZMA Decoder uses dictionary buffer and internal state structure.
+Internal state structure consumes
+  state_size = (4 + (1.5 << (lc + lp))) KB
+by default (lc=3, lp=0), state_size = 16 KB.
+
+
+How To decompress data
+----------------------
+
+LZMA Decoder (ANSI-C version) now supports 2 interfaces:
+1) Single-call Decompressing
+2) Multi-call State Decompressing (zlib-like interface)
+
+You must use external allocator:
+Example:
+void *SzAlloc(void *p, size_t size) { p = p; return malloc(size); }
+void SzFree(void *p, void *address) { p = p; free(address); }
+ISzAlloc alloc = { SzAlloc, SzFree };
+
+You can use p = p; operator to disable compiler warnings.
+
+
+Single-call Decompressing
+-------------------------
+When to use: RAM->RAM decompressing
+Compile files: LzmaDec.h + LzmaDec.c + Types.h
+Compile defines: no defines
+Memory Requirements:
+  - Input buffer: compressed size
+  - Output buffer: uncompressed size
+  - LZMA Internal Structures: state_size (16 KB for default settings) 
+
+Interface:
+  int LzmaDecode(Byte *dest, SizeT *destLen, const Byte *src, SizeT *srcLen,
+      const Byte *propData, unsigned propSize, ELzmaFinishMode finishMode, 
+      ELzmaStatus *status, ISzAlloc *alloc);
+  In: 
+    dest     - output data
+    destLen  - output data size
+    src      - input data
+    srcLen   - input data size
+    propData - LZMA properties  (5 bytes)
+    propSize - size of propData buffer (5 bytes)
+    finishMode - It has meaning only if the decoding reaches output limit (*destLen).
+         LZMA_FINISH_ANY - Decode just destLen bytes.
+         LZMA_FINISH_END - Stream must be finished after (*destLen).
+                           You can use LZMA_FINISH_END, when you know that 
+                           current output buffer covers last bytes of stream. 
+    alloc    - Memory allocator.
+
+  Out: 
+    destLen  - processed output size 
+    srcLen   - processed input size 
+
+  Output:
+    SZ_OK
+      status:
+        LZMA_STATUS_FINISHED_WITH_MARK
+        LZMA_STATUS_NOT_FINISHED 
+        LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK
+    SZ_ERROR_DATA - Data error
+    SZ_ERROR_MEM  - Memory allocation error
+    SZ_ERROR_UNSUPPORTED - Unsupported properties
+    SZ_ERROR_INPUT_EOF - It needs more bytes in input buffer (src).
+
+  If LZMA decoder sees end_marker before reaching output limit, it returns OK result,
+  and output value of destLen will be less than output buffer size limit.
+
+  You can use multiple checks to test data integrity after full decompression:
+    1) Check Result and "status" variable.
+    2) Check that output(destLen) = uncompressedSize, if you know real uncompressedSize.
+    3) Check that output(srcLen) = compressedSize, if you know real compressedSize. 
+       You must use correct finish mode in that case. */ 
+
+
+Multi-call State Decompressing (zlib-like interface)
+----------------------------------------------------
+
+When to use: file->file decompressing 
+Compile files: LzmaDec.h + LzmaDec.c + Types.h
+
+Memory Requirements:
+ - Buffer for input stream: any size (for example, 16 KB)
+ - Buffer for output stream: any size (for example, 16 KB)
+ - LZMA Internal Structures: state_size (16 KB for default settings) 
+ - LZMA dictionary (dictionary size is encoded in LZMA properties header)
+
+1) read LZMA properties (5 bytes) and uncompressed size (8 bytes, little-endian) to header:
+   unsigned char header[LZMA_PROPS_SIZE + 8];
+   ReadFile(inFile, header, sizeof(header)
+
+2) Allocate CLzmaDec structures (state + dictionary) using LZMA properties
+
+  CLzmaDec state;
+  LzmaDec_Constr(&state);
+  res = LzmaDec_Allocate(&state, header, LZMA_PROPS_SIZE, &g_Alloc);
+  if (res != SZ_OK)
+    return res;
+
+3) Init LzmaDec structure before any new LZMA stream. And call LzmaDec_DecodeToBuf in loop
+
+  LzmaDec_Init(&state);
+  for (;;)
+  {
+    ... 
+    int res = LzmaDec_DecodeToBuf(CLzmaDec *p, Byte *dest, SizeT *destLen, 
+        const Byte *src, SizeT *srcLen, ELzmaFinishMode finishMode);
+    ...
+  }
+
+
+4) Free all allocated structures
+  LzmaDec_Free(&state, &g_Alloc);
+
+For full code example, look at C/LzmaUtil/LzmaUtil.c code.
+
+
+How To compress data
+--------------------
+
+Compile files: LzmaEnc.h + LzmaEnc.c + Types.h +
+LzFind.c + LzFind.h + LzFindMt.c + LzFindMt.h + LzHash.h
+
+Memory Requirements:
+  - (dictSize * 11.5 + 6 MB) + state_size
+
+Lzma Encoder can use two memory allocators:
+1) alloc - for small arrays.
+2) allocBig - for big arrays.
+
+For example, you can use Large RAM Pages (2 MB) in allocBig allocator for 
+better compression speed. Note that Windows has bad implementation for 
+Large RAM Pages. 
+It's OK to use same allocator for alloc and allocBig.
+
+
+Single-call Compression with callbacks
+--------------------------------------
+
+Check C/LzmaUtil/LzmaUtil.c as example, 
+
+When to use: file->file decompressing 
+
+1) you must implement callback structures for interfaces:
+ISeqInStream
+ISeqOutStream
+ICompressProgress
+ISzAlloc
+
+static void *SzAlloc(void *p, size_t size) { p = p; return MyAlloc(size); }
+static void SzFree(void *p, void *address) {  p = p; MyFree(address); }
+static ISzAlloc g_Alloc = { SzAlloc, SzFree };
+
+  CFileSeqInStream inStream;
+  CFileSeqOutStream outStream;
+
+  inStream.funcTable.Read = MyRead;
+  inStream.file = inFile;
+  outStream.funcTable.Write = MyWrite;
+  outStream.file = outFile;
+
+
+2) Create CLzmaEncHandle object;
+
+  CLzmaEncHandle enc;
+
+  enc = LzmaEnc_Create(&g_Alloc);
+  if (enc == 0)
+    return SZ_ERROR_MEM;
+
+
+3) initialize CLzmaEncProps properties;
+
+  LzmaEncProps_Init(&props);
+
+  Then you can change some properties in that structure.
+
+4) Send LZMA properties to LZMA Encoder
+
+  res = LzmaEnc_SetProps(enc, &props);
+
+5) Write encoded properties to header
+
+    Byte header[LZMA_PROPS_SIZE + 8];
+    size_t headerSize = LZMA_PROPS_SIZE;
+    UInt64 fileSize;
+    int i;
+
+    res = LzmaEnc_WriteProperties(enc, header, &headerSize);
+    fileSize = MyGetFileLength(inFile);
+    for (i = 0; i < 8; i++)
+      header[headerSize++] = (Byte)(fileSize >> (8 * i));
+    MyWriteFileAndCheck(outFile, header, headerSize)
+
+6) Call encoding function:
+      res = LzmaEnc_Encode(enc, &outStream.funcTable, &inStream.funcTable, 
+        NULL, &g_Alloc, &g_Alloc);
+
+7) Destroy LZMA Encoder Object
+  LzmaEnc_Destroy(enc, &g_Alloc, &g_Alloc);
+
+
+If callback function return some error code, LzmaEnc_Encode also returns that code
+or it can return the code like SZ_ERROR_READ, SZ_ERROR_WRITE or SZ_ERROR_PROGRESS.
+
+
+Single-call RAM->RAM Compression
+--------------------------------
+
+Single-call RAM->RAM Compression is similar to Compression with callbacks,
+but you provide pointers to buffers instead of pointers to stream callbacks:
+
+HRes LzmaEncode(Byte *dest, SizeT *destLen, const Byte *src, SizeT srcLen,
+    CLzmaEncProps *props, Byte *propsEncoded, SizeT *propsSize, int writeEndMark, 
+    ICompressProgress *progress, ISzAlloc *alloc, ISzAlloc *allocBig);
+
+Return code:
+  SZ_OK               - OK
+  SZ_ERROR_MEM        - Memory allocation error 
+  SZ_ERROR_PARAM      - Incorrect paramater
+  SZ_ERROR_OUTPUT_EOF - output buffer overflow
+  SZ_ERROR_THREAD     - errors in multithreading functions (only for Mt version)
+
+
+
+Defines
+-------
+
+_LZMA_SIZE_OPT - Enable some optimizations in LZMA Decoder to get smaller executable code.
+
+_LZMA_PROB32   - It can increase the speed on some 32-bit CPUs, but memory usage for 
+                 some structures will be doubled in that case.
+
+_LZMA_UINT32_IS_ULONG  - Define it if int is 16-bit on your compiler and long is 32-bit.
+
+_LZMA_NO_SYSTEM_SIZE_T  - Define it if you don't want to use size_t type.
+
+
+_7ZIP_PPMD_SUPPPORT - Define it if you don't want to support PPMD method in AMSI-C .7z decoder.
+
+
+C++ LZMA Encoder/Decoder 
+~~~~~~~~~~~~~~~~~~~~~~~~
+C++ LZMA code use COM-like interfaces. So if you want to use it, 
+you can study basics of COM/OLE.
+C++ LZMA code is just wrapper over ANSI-C code.
+
+
+C++ Notes
+~~~~~~~~~~~~~~~~~~~~~~~~
+If you use some C++ code folders in 7-Zip (for example, C++ code for .7z handling),
+you must check that you correctly work with "new" operator.
+7-Zip can be compiled with MSVC 6.0 that doesn't throw "exception" from "new" operator.
+So 7-Zip uses "CPP\Common\NewHandler.cpp" that redefines "new" operator:
+operator new(size_t size)
+{
+  void *p = ::malloc(size);
+  if (p == 0)
+    throw CNewException();
+  return p;
+}
+If you use MSCV that throws exception for "new" operator, you can compile without 
+"NewHandler.cpp". So standard exception will be used. Actually some code of 
+7-Zip catches any exception in internal code and converts it to HRESULT code.
+So you don't need to catch CNewException, if you call COM interfaces of 7-Zip.

+
+Compiling under Unix/Linux
+--------------------------
+Check this site for Posix/Linux version:
+http://sourceforge.net/projects/p7zip/
+
+
+Notes:
+------
+7-Zip consists of COM modules (DLL files).
+But 7-Zip doesn't use standard COM interfaces for creating objects.
+Look at
+7zip\UI\Client7z folder for example of using DLL files of 7-Zip. 
+Some DLL files can use other DLL files from 7-Zip.
+If you don't like it, you must use standalone version of DLL.
+To compile standalone version of DLL you must include all used parts
+to project and define some defs. 
+For example, 7zip\Bundles\Format7z is a standalone version  of 7z.dll 
+that works with 7z format. So you can use such DLL in your project 
+without additional DLL files.

+	p7zip 9.20
+	==========
+
+Homepage : http://p7zip.sourceforge.net/
+
+p7zip is a port of the Windows programs 7z.exe and 7za.exe provided by 7-zip.
+
+7-zip is a file archiver with the highest compression ratio.
+Homepage : www.7-zip.org
+
+  7z uses plugins (7z.so and Codecs/Rar29.so) to handle archives.
+  7za is a stand-alone executable.
+  7za handles less archive formats than 7z.exe.
+  7zr is a light stand-alone executable that supports only 7z/LZMA/BCJ/BCJ2.
+
+NEW:
+  7zG : see GUI/readme.txt
+
+CAUTION :
+---------
+
+- FIRST : DO NOT USE the 7-zip format for backup purpose on Linux/Unix because :
+  - 7-zip does not store the owner/group of the file
+
+  On Linux/Unix, in order to backup directories you must use tar !
+  to backup a directory  : tar cf - directory | 7za a -si directory.tar.7z
+  to restore your backup : 7za x -so directory.tar.7z | tar xf -
+
+- if you want to send files and directories (not the owner of file)
+  to others Unix/MacOS/Windows users, you can use the 7-zip format.
+
+  example : 7za a directory.7z  directory
+
+  do not use "-r" because this flag does not do what you think
+  do not use directory/* because of ".*" files
+   (example : "directory/*" does not match "directory/.profile")
+
+
+BUILD :
+-------
+
+  If you have downloaded the "bin" package,
+	use directly the program bin/7za.
+	(tested on Redhat 9.0, Fedora 2, Mandrake 10.0, Debian 3.0)
+	As the program is statically linked, its should run on many x86 or amd64 linux.
+
+  If you have downloaded the "source" package,
+
+	According to your OS, copy makefile.linux,
+	makefile.freebsd, makefile.cygwin, ...
+        over makefile.machine
+
+  Example : building 7za, 7z (with its plugins), 7zr and Client7z and passing the internal tests
+	cp makefile.linux_x86_asm_gcc_4 makefile.linux
+	make all_test
+
+
+	If you want to make a parallel build on a 4 cpu machine : make -j 4 TARGET
+
+	If you have trouble, try : make -f makefile.oldmake TARGET
+
+	make depend   : to rebuild the makefile.depend
+	make clean    : to clean all directories
+	make          : to build bin/7za
+	make sfx      : to build bin/7zCon.sfx (7za can now create SFX archive)
+	make 7z       : to build bin/7z and its plugins :
+                          - "bin/7z.so" (GNU LGPL + AES code license)
+                          - "bin/Codecs/Rar29.so" (GNU LGPL + unRAR restriction)
+	make 7zr      : to build bin/7zr
+	make all      : to build bin/7za and bin/7zCon.sfx
+	make all2     : to build bin/7za, bin/7z (with its plugins) and bin/7zCon.sfx
+	make all3     : to build bin/7za, bin/7z (with its plugins), bin/7zr and bin/7zCon.sfx
+	make test     : to test bin/7za (extracting, archiving, password ...)
+	make test_7z  : to test bin/7z  (extracting, archiving, password ...)
+	make test_7zr : to test bin/7zr (extracting, archiving, ...)
+
+	make 7zG      : to build bin/7zG and its plugins :
+                          - "bin/7z.so" (GNU LGPL + AES code license)
+                          - "bin/Codecs/Rar29.so" (GNU LGPL + unRAR restriction)
+	make test_7zG : to test bin/7zG (extracting, archiving, ...)
+

+                                    plugins don't work because C++ constructors are not called !)
+
+
+BUILD with cmake
+----------------
+  You can only build 7za.
+ 
+  cd CPP/7zip/CMAKE
+
+  edit generate.sh to choose your target
+
+  ./generate.sh
+
+  the cmake project for the target is in "CPP/7zip/CMAKE/Alone".
+
+  For the target "Unix Makefiles", use "make" to compile
+
+  For others target, use the IDE (CodeBlocks, KDevelop3, Eclipse CDT4)
+
+INSTALL :
+---------
+
+  method 1
+  --------
+  - edit install.sh to change DEST_HOME
+  - ./install.sh : to install
+  Remark : you must be "root" to install 7za in the directory "/usr/local"
+
+  method 2
+  --------
+  - 7za is a stand-alone program, you can put this program where you want.
+  example :  cp bin/7za /usr/local/bin/7za
+
+  - 7z needs its plugins. You must copy the file 7z, 7z.so
+    and the directory Codecs in the same destination directory.
+
+  - if you want to be able to create SFX archive, copy bin/7zCon.sfx
+  to the directory where 7za or 7z can be found.
+  
+
+USAGE:
+------
+  Remark : you can replace 7za with 7z.
+
+  7za t archive.7z  : tests files in the archive archive.7z
+  7za l archive.7z  : lists all files from archive archive.7z
+  7za x archive.7z  : extracts all files from archive archive.7z
+                   to the current directory
+
+  7za a archive.7z file1 fileN : add files to the archive archive.7z
+
+  7za a archive.7z  dir1 :  add all files and subdirectories from directory "dir1" to archive archive.7z 
+
+  CAUTION : do not use the flag "-r" unless you know what you are doing ...
+
+  7za a -sfx archive.exe dir1 : add all files from directory "dir1" to SFX archive archive.exe 
+  (Remark : SFX archive MUST end with ".exe")
+
+  You can also add or extract files to/from .zip or .tar archives.
+  You can also compress/uncompress .gz or .bz2 files.
+
+  7za a -tzip   archive.zip file file2 file3
+  7za a -ttar   archive.tar file
+  7za a -tgzip  file.gz     file
+  7za a -tbzip2 archive.bz2 file
+
+  You can use password for archives:
+  7za a -pmy_password archive.7z  dir1
+
+  For .7z archive only, you can enable archive header encryption with "-mhe"
+  7za a -mhe=on -pmy_password archive.7z  dir1
+
+  For more, see the documentation of 7za.exe in DOCS/MANUAL directory
+  7za a -t7z  -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on archive.7z  dir1
+      adds all files from directory "dir1" to archive archive.7z
+      using "ultra settings".
+      -t7z     : 7z archive
+      -m0=lzma : lzma method
+      -mx=9    : level of compression = 9 (Ultra)
+      -mfb=64  : number of fast bytes for LZMA = 64
+      -md=32m  : dictionary size = 32 megabytes
+      -ms=on   : solid archive = on
+
+  To use the new codec "lzma2"
+  7za a -m0=lzma2 archive.7z directory
+
+
+BENCHMARKS :
+------------
+  7za b : bench LZMA codec
+  7z b -mm=crc : make internal crc check.
+
+
+hugetlbfs (large pages)
+------------
+
+  Using huges pages in Linux requires some preparations.
+  First, make sure your running kernel has support for hugetlbfs compiled in:
+
+  ~$ grep hugetlbfs /proc/filesystems
+  nodev       hugetlbfs
+
+  You can view your current huge page configuration like this:
+
+  ~$ grep Huge /proc/meminfo
+  HugePages_Total:       0
+  HugePages_Free:        0
+  HugePages_Rsvd:        0
+  HugePages_Surp:        0
+  Hugepagesize:       2048 kB
+
+  In this case the size of a huge page is 2 MiB.
+  So, if you have 2 GiB of RAM and want to reserve 512 MiB for huge pages,
+  you would need 256 pages.
+
+  Do the following as root:
+
+  ~# echo 296 >/proc/sys/vm/nr_hugepages
+  ~# grep Huge /proc/meminfo
+  HugePages_Total:     296
+  HugePages_Free:      296
+  HugePages_Rsvd:        0
+  HugePages_Surp:        0
+  Hugepagesize:       2048 kB
+
+  Finally, make access from user space possible:
+
+  ~# mkdir /hugepages
+  ~# mount -t hugetlbfs -o rw,nosuid,nodev,noexec,noatime none /hugepages
+  ~# chmod 1777 /hugepages
+
+  Option 1 : Now huge pages are configured. 
+           In your shell, set the environment variable HUGETLB_PATH to the mount point:
+           ~$ export HUGETLB_PATH=/hugepages
+  or
+  
+  Option 2 : Let p7zip find out the first directory with the type "hugetlbfs"
+
+
+  To enable huge page use in p7zip, pass the '-slp' switch to it.
+  Ex: 7za -slp a t.7z dir
+
+
+  
+  If you want this to be a permanent setup :
+  - mkdir /hugepages
+
+  - add an entry to your /etc/fstab so that when you reboot your computer,
+    your hugetlbfs will mount automatically :
+    hugetlbfs       /hugepages  hugetlbfs     rw,nosuid,nodev,noexec,noatime   0 0
+
+  - add this in your /etc/rc.local :
+    chmod 1777 /hugepages
+    echo 296 >  /proc/sys/vm/nr_hugepages
+
+  optional : export HUGETLB_PATH=/hugepages
+
+  To enable huge page use in p7zip, pass the '-slp' switch to it : 7za -slp b
+
+
+  Remark : with current CPU : "7za -slp b" is not faster than "7za b".
+           If you want to see some speedup, compress at least 300MB
+           Ex : 7za -slp -mx=9 -a big_file.tar.7z  big_file.tar
+
+
+LICENSE :
+---------
+  please read DOCS/License.txt.
+
+LIMITATIONS from 7-zip :
+------------------------
+
+  - does not support uid/gid for the .tar format (so, use tar on Unix)
+
+LIMITATIONS for Unix version only :
+-----------------------------------
+
+  - can handle properly UNICODE filenames only if the environment is UTF-8.
+  Example : export LANG=en_US.UTF-8 ; unset LC_CTYPE
+  Remark  : see the possible values for LANG in the directory 
+            - /usr/lib/locale   : Fedora 2 / Solaris 8
+            - /usr/share/locale : OpenBSD / Debian / FreeBSD / MacOS X / Mandrake 10.1 / NetBSD
+
+	On Linux, to display the available locales : locale -a
+
+  p7zip relies on LC_CTYPE and then on LANG to convert name to/from UNICODE.
+  the command "locale" should display these environment variables.
+  you can also do "echo $LC_CTYPE" and "echo $LANG".
+
+  If you do not plan to export your archive, you can use the flag "-no-utf16".
+  Usage :
+    7za a -no-utf16 archive.7z dirOrFile1 ... dirOrFileN
+    7za t -no-utf16 archive.7z
+    7za l -no-utf16 archive.7z
+    7za x -no-utf16 archive.7z
+ 
+  - ignores Windows file access permissions (files are created with default permissions)
+
+  see also TODO file.
+
+DEVELOPPER CORNER:
+------------------
+
+  - WaitForMultipleObject has no equivalence on Unix.
+  - Events don't exist.
+  - sizeof(wchar_t) = 4 with GCC (2 with MS VC++)
+  - "FIXME" in source code indicates that you should add codes to better handle all cases.
+
+  - "FIXED" in source code indicates that the original code has been changed to work in Unix environment.
+
+  see also TODO file.

+-------------
+level - compression level: 0 <= level <= 9, the default value for "level" is 5.
+
+dictSize - The dictionary size in bytes. The maximum value is
+        128 MB = (1 << 27) bytes for 32-bit version
+          1 GB = (1 << 30) bytes for 64-bit version
+     The default value is 16 MB = (1 << 24) bytes, for level = 5.
+     It's recommended to use the dictionary that is larger than 4 KB and
+     that can be calculated as (1 << N) or (3 << N) sizes.
+     For better compression ratio dictSize must be >= inSize.
+
+filterMode:
+    SZ_FILTER_NO   - no Filter
+    SZ_FILTER_YES  - x86 Filter
+    SZ_FILTER_AUTO - it tries both alternatives to select best.
+              Encoder will use 2 or 3 passes:
+              2 passes when FILTER_NO provides better compression.
+              3 passes when FILTER_YES provides better compression.
+
+Lzma86Encode allocates Data with MyAlloc functions.
+RAM Requirements for compressing:
+  RamSize = dictionarySize * 11.5 + 6MB + FilterBlockSize
+      filterMode     FilterBlockSize
+     SZ_FILTER_NO         0
+     SZ_FILTER_YES      inSize

+ 
+  The default value for "level" is 5.
+
+  algo = 0 means fast method
+  algo = 1 means normal method
+
+dictSize - The dictionary size in bytes. The maximum value is
+        128 MB = (1 << 27) bytes for 32-bit version
+          1 GB = (1 << 30) bytes for 64-bit version
+     The default value is 16 MB = (1 << 24) bytes.
+     It's recommended to use the dictionary that is larger than 4 KB and
+     that can be calculated as (1 << N) or (3 << N) sizes.
+
+lc - The number of literal context bits (high bits of previous literal).
+     It can be in the range from 0 to 8. The default value is 3.
+     Sometimes lc=4 gives the gain for big files.
+
+lp - The number of literal pos bits (low bits of current position for literals).
+     It can be in the range from 0 to 4. The default value is 0.
+     The lp switch is intended for periodical data when the period is equal to 2^lp.
+     For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's
+     better to set lc=0, if you change lp switch.
+
+pb - The number of pos bits (low bits of current position).
+     It can be in the range from 0 to 4. The default value is 2.
+     The pb switch is intended for periodical data when the period is equal 2^pb.
+
+fb - Word size (the number of fast bytes).
+     It can be in the range from 5 to 273. The default value is 32.
+     Usually, a big number gives a little bit better compression ratio and
+     slower compression process.
+
+numThreads - The number of thereads. 1 or 2. The default value is 2.
+     Fast mode (algo = 0) can use only 1 thread.

+7z ANSI-C Decoder 4.62
+----------------------
+
+7z ANSI-C provides 7z/LZMA decoding.
+7z ANSI-C version is simplified version ported from C++ code.
+
+LZMA is default and general compression method of 7z format
+in 7-Zip compression program (www.7-zip.org). LZMA provides high 
+compression ratio and very fast decompression.
+
+
+LICENSE
+-------
+
+7z ANSI-C Decoder is part of the LZMA SDK.
+LZMA SDK is written and placed in the public domain by Igor Pavlov.
+
+Files
+---------------------
+
+7zDecode.*   - Low level 7z decoding
+7zExtract.*  - High level 7z decoding
+7zHeader.*   - .7z format constants
+7zIn.*       - .7z archive opening
+7zItem.*     - .7z structures
+7zMain.c     - Test application
+
+
+How To Use
+----------
+
+You must download 7-Zip program from www.7-zip.org.
+
+You can create .7z archive with 7z.exe or 7za.exe:
+
+  7za.exe a archive.7z *.htm -r -mx -m0fb=255
+
+If you have big number of files in archive, and you need fast extracting, 
+you can use partly-solid archives:
+  
+  7za.exe a archive.7z *.htm -ms=512K -r -mx -m0fb=255 -m0d=512K
+
+In that example 7-Zip will use 512KB solid blocks. So it needs to decompress only 
+512KB for extracting one file from such archive.
+
+
+Limitations of current version of 7z ANSI-C Decoder
+---------------------------------------------------
+
+ - It reads only "FileName", "Size", "LastWriteTime" and "CRC" information for each file in archive.
+ - It supports only LZMA and Copy (no compression) methods with BCJ or BCJ2 filters.
+ - It converts original UTF-16 Unicode file names to UTF-8 Unicode file names.
+ 
+These limitations will be fixed in future versions.
+
+
+Using 7z ANSI-C Decoder Test application:
+-----------------------------------------
+
+Usage: 7zDec <command> <archive_name>
+
+<Command>:
+  e: Extract files from archive
+  l: List contents of archive
+  t: Test integrity of archive
+
+Example: 
+
+  7zDec l archive.7z
+
+lists contents of archive.7z
+
+  7zDec e archive.7z
+
+extracts files from archive.7z to current folder.
+
+
+How to use .7z Decoder
+----------------------
+
+Memory allocation
+~~~~~~~~~~~~~~~~~
+
+7z Decoder uses two memory pools:
+1) Temporary pool
+2) Main pool
+Such scheme can allow you to avoid fragmentation of allocated blocks.
+
+
+Steps for using 7z decoder
+--------------------------
+
+Use code at 7zMain.c as example.
+
+1) Declare variables:
+  inStream                 /* implements ILookInStream interface */
+  CSzArEx db;              /* 7z archive database structure */
+  ISzAlloc allocImp;       /* memory functions for main pool */
+  ISzAlloc allocTempImp;   /* memory functions for temporary pool */
+
+2) call CrcGenerateTable(); function to initialize CRC structures.
+
+3) call SzArEx_Init(&db); function to initialize db structures.
+
+4) call SzArEx_Open(&db, inStream, &allocMain, &allocTemp) to open archive
+
+This function opens archive "inStream" and reads headers to "db".
+All items in "db" will be allocated with "allocMain" functions.
+SzArEx_Open function allocates and frees temporary structures by "allocTemp" functions.
+
+5) List items or Extract items
+
+  Listing code:
+  ~~~~~~~~~~~~~
+    {
+      UInt32 i;
+      for (i = 0; i < db.db.NumFiles; i++)
+      {
+        CFileItem *f = db.db.Files + i;
+        printf("%10d  %s\n", (int)f->Size, f->Name);
+      }
+    }
+
+  Extracting code:
+  ~~~~~~~~~~~~~~~~
+
+  SZ_RESULT SzAr_Extract(
+    CArchiveDatabaseEx *db,
+    ILookInStream *inStream, 
+    UInt32 fileIndex,         /* index of file */
+    UInt32 *blockIndex,       /* index of solid block */
+    Byte **outBuffer,         /* pointer to pointer to output buffer (allocated with allocMain) */
+    size_t *outBufferSize,    /* buffer size for output buffer */
+    size_t *offset,           /* offset of stream for required file in *outBuffer */
+    size_t *outSizeProcessed, /* size of file in *outBuffer */
+    ISzAlloc *allocMain,
+    ISzAlloc *allocTemp);
+
+  If you need to decompress more than one file, you can send these values from previous call:
+    blockIndex, 
+    outBuffer, 
+    outBufferSize,
+  You can consider "outBuffer" as cache of solid block. If your archive is solid, 
+  it will increase decompression speed.
+
+  After decompressing you must free "outBuffer":
+  allocImp.Free(outBuffer);
+
+6) call SzArEx_Free(&db, allocImp.Free) to free allocated items in "db".
+
+
+
+
+Memory requirements for .7z decoding 
+------------------------------------
+
+Memory usage for Archive opening:
+  - Temporary pool:
+     - Memory for uncompressed .7z headers
+     - some other temporary blocks
+  - Main pool:
+     - Memory for database: 
+       Estimated size of one file structures in solid archive:
+         - Size (4 or 8 Bytes)
+         - CRC32 (4 bytes)
+         - LastWriteTime (8 bytes)
+         - Some file information (4 bytes)
+         - File Name (variable length) + pointer + allocation structures
+
+Memory usage for archive Decompressing:
+  - Temporary pool:
+     - Memory for LZMA decompressing structures
+  - Main pool:
+     - Memory for decompressed solid block
+     - Memory for temprorary buffers, if BCJ2 fileter is used. Usually these 
+       temprorary buffers can be about 15% of solid block size. 
+  
+
+7z Decoder doesn't allocate memory for compressed blocks. 
+Instead of this, you must allocate buffer with desired 
+size before calling 7z Decoder. Use 7zMain.c as example.

+
+Defines
+-------
+
+_SZ_ALLOC_DEBUG   - define it if you want to debug alloc/free operations to stderr.

+7z Format description (4.59)
+----------------------------
+
+This file contains description of 7z archive format. 
+7z archive can contain files compressed with any method.
+See "Methods.txt" for description for defined compressing methods.
+
+
+Format structure Overview
+-------------------------
+
+Some fields can be optional.

+
+Notes about Notation and encoding
+---------------------------------
+
+7z uses little endian encoding.
+
+7z archive format has optional headers that are marked as
+[]
+Header
+[]
+
+REAL_UINT64 means real UINT64.
+
+UINT64 means real UINT64 encoded with the following scheme:
+
+  Size of encoding sequence depends from first byte:
+  First_Byte  Extra_Bytes        Value
+  (binary)   
+  0xxxxxxx               : ( xxxxxxx           )
+  10xxxxxx    BYTE y[1]  : (  xxxxxx << (8 * 1)) + y
+  110xxxxx    BYTE y[2]  : (   xxxxx << (8 * 2)) + y
+  ...
+  1111110x    BYTE y[6]  : (       x << (8 * 6)) + y
+  11111110    BYTE y[7]  :                         y

+7-Zip method IDs (9.18)
+-----------------------
+
+Each compression or crypto method in 7z has unique binary value (ID).
+The length of ID in bytes is arbitrary but it can not exceed 63 bits (8 bytes).
+
+If you want to add some new ID, you have two ways:
+1) Write request for allocating IDs to 7-zip developers.
+2) Generate 8-bytes ID:
+
+    3F ZZ ZZ ZZ ZZ ZZ MM MM 
+
+    3F              - Prefix for random IDs (1 byte)
+    ZZ ZZ ZZ ZZ ZZ  - Developer ID (5 bytes). Use real random bytes. 
+                      
+    MM MM           - Method ID (2 bytes)
+
+    You can notify 7-Zip developers about your Developer ID / Method ID.
+
+    Note: Use new ID only if old codec can not decode data encoded with new version.

+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+          Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+      GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+          NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+         END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990

+  
+4.61           2008-11-23
+-------------------------
+- Bug in ver. 4.58+ was fixed:
+   7-Zip didn't use any -m* switch after -mtc, -mcl or -mcu for .zip archives. 
+- Bug in .CAB code was fixed. 7-Zip didn't show some empty files,

+-------------------------
+- Speed optimizations for LZMA decoding. Now it uses C code instead of C++.
+- 7-Zip now has 128 MB dictionary limit for 32-bit version:
+  It's for speed optimization: kNumLogBits = 9 + sizeof(size_t) / 2;
+- TAR: 'D' link flag support.
+- 7-Zip now can unpack multivolume RAR archives created with 
+  "old style volume names" scheme (-vn switch) and names *.001, *.002, ...
+- Fixed bugs:
+  - 7-Zip FM could not copy / move files to root network folders like \\COMPNAME\FOLDERNAME\
+    In case of move it removed original files.
+  - SFX-WIN: if there are errors, it still could return 0.
+  - ZIP (.XPS file) isZip64 && thisDiskNumber16 == 0xFFFF.
+  - ZIP name updating:
+      If zip file contains extra field and you try to change properties of files,
+      7-zip tries to delete all extra fileds (except for WzAES).
+      And that code could hang.
+  -  7-Zip GUI didn't suggest BZip2 dictionary size used in previous run.
+  -  If creation time stamp was included in .RAR archive, 7-zip used creation time stamp 
+     as modification time stamp.

+LZMA SDK 9.20
+-------------
+
+LZMA SDK provides the documentation, samples, header files, libraries, 
+and tools you need to develop applications that use LZMA compression.
+
+LZMA is default and general compression method of 7z format
+in 7-Zip compression program (www.7-zip.org). LZMA provides high 
+compression ratio and very fast decompression.
+
+LZMA is an improved version of famous LZ77 compression algorithm. 
+It was improved in way of maximum increasing of compression ratio,
+keeping high decompression speed and low memory requirements for 
+decompressing.
+
+
+

+
+
+LZMA features
+-------------
+  - Variable dictionary size (up to 1 GB)
+  - Estimated compressing speed: about 2 MB/s on 2 GHz CPU
+  - Estimated decompressing speed: 
+      - 20-30 MB/s on 2 GHz Core 2 or AMD Athlon 64
+      - 1-2 MB/s on 200 MHz ARM, MIPS, PowerPC or other simple RISC
+  - Small memory requirements for decompressing (16 KB + DictionarySize)
+  - Small code size for decompressing: 5-8 KB
+
+LZMA decoder uses only integer operations and can be 
+implemented in any modern 32-bit CPU (or on 16-bit CPU with some conditions).
+
+Some critical operations that affect the speed of LZMA decompression:
+  1) 32*16 bit integer multiply
+  2) Misspredicted branches (penalty mostly depends from pipeline length)
+  3) 32-bit shift and arithmetic operations
+
+The speed of LZMA decompressing mostly depends from CPU speed.
+Memory speed has no big meaning. But if your CPU has small data cache, 
+overall weight of memory speed will slightly increase.
+
+
+How To Use
+----------
+
+Using LZMA encoder/decoder executable
+--------------------------------------
+
+Usage:  LZMA <e|d> inputFile outputFile [<switches>...]
+
+  e: encode file
+
+  d: decode file
+
+  b: Benchmark. There are two tests: compressing and decompressing 
+     with LZMA method. Benchmark shows rating in MIPS (million 
+     instructions per second). Rating value is calculated from 
+     measured speed and it is normalized with Intel's Core 2 results.
+     Also Benchmark checks possible hardware errors (RAM 
+     errors in most cases). Benchmark uses these settings:
+     (-a1, -d21, -fb32, -mfbt4). You can change only -d parameter. 
+     Also you can change the number of iterations. Example for 30 iterations:
+       LZMA b 30
+     Default number of iterations is 10.
+
+<Switches>
+  
+
+  -a{N}:  set compression mode 0 = fast, 1 = normal
+          default: 1 (normal)
+
+  d{N}:   Sets Dictionary size - [0, 30], default: 23 (8MB)
+          The maximum value for dictionary size is 1 GB = 2^30 bytes.
+          Dictionary size is calculated as DictionarySize = 2^N bytes. 
+          For decompressing file compressed by LZMA method with dictionary 
+          size D = 2^N you need about D bytes of memory (RAM).
+
+  -fb{N}: set number of fast bytes - [5, 273], default: 128
+          Usually big number gives a little bit better compression ratio 
+          and slower compression process.
+
+  -lc{N}: set number of literal context bits - [0, 8], default: 3
+          Sometimes lc=4 gives gain for big files.
+
+  -lp{N}: set number of literal pos bits - [0, 4], default: 0
+          lp switch is intended for periodical data when period is 
+          equal 2^N. For example, for 32-bit (4 bytes) 
+          periodical data you can use lp=2. Often it's better to set lc0, 
+          if you change lp switch.
+
+  -pb{N}: set number of pos bits - [0, 4], default: 2
+          pb switch is intended for periodical data 
+          when period is equal 2^N.
+
+  -mf{MF_ID}: set Match Finder. Default: bt4. 
+              Algorithms from hc* group doesn't provide good compression 
+              ratio, but they often works pretty fast in combination with 
+              fast mode (-a0).
+
+              Memory requirements depend from dictionary size 
+              (parameter "d" in table below). 
+
+               MF_ID     Memory                   Description
+
+                bt2    d *  9.5 + 4MB  Binary Tree with 2 bytes hashing.
+                bt3    d * 11.5 + 4MB  Binary Tree with 3 bytes hashing.
+                bt4    d * 11.5 + 4MB  Binary Tree with 4 bytes hashing.
+                hc4    d *  7.5 + 4MB  Hash Chain with 4 bytes hashing.
+
+  -eos:   write End Of Stream marker. By default LZMA doesn't write 
+          eos marker, since LZMA decoder knows uncompressed size 
+          stored in .lzma file header.
+
+  -si:    Read data from stdin (it will write End Of Stream marker).
+  -so:    Write data to stdout
+
+
+Examples:
+
+1) LZMA e file.bin file.lzma -d16 -lc0 
+
+compresses file.bin to file.lzma with 64 KB dictionary (2^16=64K)  
+and 0 literal context bits. -lc0 allows to reduce memory requirements 
+for decompression.
+
+
+2) LZMA e file.bin file.lzma -lc0 -lp2
+
+compresses file.bin to file.lzma with settings suitable 
+for 32-bit periodical data (for example, ARM or MIPS code).
+
+3) LZMA d file.lzma file.bin
+
+decompresses file.lzma to file.bin.
+
+
+Compression ratio hints
+-----------------------
+
+Recommendations
+---------------
+
+To increase the compression ratio for LZMA compressing it's desirable 
+to have aligned data (if it's possible) and also it's desirable to locate
+data in such order, where code is grouped in one place and data is 
+grouped in other place (it's better than such mixing: code, data, code,
+data, ...).
+
+
+Filters
+-------
+You can increase the compression ratio for some data types, using
+special filters before compressing. For example, it's possible to 
+increase the compression ratio on 5-10% for code for those CPU ISAs: 
+x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.
+
+You can find C source code of such filters in C/Bra*.* files
+
+You can check the compression ratio gain of these filters with such 
+7-Zip commands (example for ARM code):
+No filter:
+  7z a a1.7z a.bin -m0=lzma
+
+With filter for little-endian ARM code:
+  7z a a2.7z a.bin -m0=arm -m1=lzma        
+
+It works in such manner:
+Compressing    = Filter_encoding + LZMA_encoding
+Decompressing  = LZMA_decoding + Filter_decoding
+
+Compressing and decompressing speed of such filters is very high,
+so it will not increase decompressing time too much.
+Moreover, it reduces decompression time for LZMA_decoding, 
+since compression ratio with filtering is higher.
+
+These filters convert CALL (calling procedure) instructions 
+from relative offsets to absolute addresses, so such data becomes more 
+compressible.
+
+For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.

+
+ANSI-C LZMA Decoder
+~~~~~~~~~~~~~~~~~~~
+
+Please note that interfaces for ANSI-C code were changed in LZMA SDK 4.58.
+If you want to use old interfaces you can download previous version of LZMA SDK
+from sourceforge.net site.
+
+To use ANSI-C LZMA Decoder you need the following files:
+1) LzmaDec.h + LzmaDec.c + Types.h
+LzmaUtil/LzmaUtil.c is example application that uses these files.
+
+
+Memory requirements for LZMA decoding
+-------------------------------------
+
+Stack usage of LZMA decoding function for local variables is not 
+larger than 200-400 bytes.
+
+LZMA Decoder uses dictionary buffer and internal state structure.
+Internal state structure consumes
+  state_size = (4 + (1.5 << (lc + lp))) KB
+by default (lc=3, lp=0), state_size = 16 KB.
+
+
+How To decompress data
+----------------------
+
+LZMA Decoder (ANSI-C version) now supports 2 interfaces:
+1) Single-call Decompressing
+2) Multi-call State Decompressing (zlib-like interface)
+
+You must use external allocator:
+Example:
+void *SzAlloc(void *p, size_t size) { p = p; return malloc(size); }
+void SzFree(void *p, void *address) { p = p; free(address); }
+ISzAlloc alloc = { SzAlloc, SzFree };
+
+You can use p = p; operator to disable compiler warnings.
+
+
+Single-call Decompressing
+-------------------------
+When to use: RAM->RAM decompressing
+Compile files: LzmaDec.h + LzmaDec.c + Types.h
+Compile defines: no defines
+Memory Requirements:
+  - Input buffer: compressed size
+  - Output buffer: uncompressed size
+  - LZMA Internal Structures: state_size (16 KB for default settings) 
+
+Interface:
+  int LzmaDecode(Byte *dest, SizeT *destLen, const Byte *src, SizeT *srcLen,
+      const Byte *propData, unsigned propSize, ELzmaFinishMode finishMode, 
+      ELzmaStatus *status, ISzAlloc *alloc);
+  In: 
+    dest     - output data
+    destLen  - output data size
+    src      - input data
+    srcLen   - input data size
+    propData - LZMA properties  (5 bytes)
+    propSize - size of propData buffer (5 bytes)
+    finishMode - It has meaning only if the decoding reaches output limit (*destLen).
+         LZMA_FINISH_ANY - Decode just destLen bytes.
+         LZMA_FINISH_END - Stream must be finished after (*destLen).
+                           You can use LZMA_FINISH_END, when you know that 
+                           current output buffer covers last bytes of stream. 
+    alloc    - Memory allocator.
+
+  Out: 
+    destLen  - processed output size 
+    srcLen   - processed input size 
+
+  Output:
+    SZ_OK
+      status:
+        LZMA_STATUS_FINISHED_WITH_MARK
+        LZMA_STATUS_NOT_FINISHED 
+        LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK
+    SZ_ERROR_DATA - Data error
+    SZ_ERROR_MEM  - Memory allocation error
+    SZ_ERROR_UNSUPPORTED - Unsupported properties
+    SZ_ERROR_INPUT_EOF - It needs more bytes in input buffer (src).
+
+  If LZMA decoder sees end_marker before reaching output limit, it returns OK result,
+  and output value of destLen will be less than output buffer size limit.
+
+  You can use multiple checks to test data integrity after full decompression:
+    1) Check Result and "status" variable.
+    2) Check that output(destLen) = uncompressedSize, if you know real uncompressedSize.
+    3) Check that output(srcLen) = compressedSize, if you know real compressedSize. 
+       You must use correct finish mode in that case. */ 
+
+
+Multi-call State Decompressing (zlib-like interface)
+----------------------------------------------------
+
+When to use: file->file decompressing 
+Compile files: LzmaDec.h + LzmaDec.c + Types.h
+
+Memory Requirements:
+ - Buffer for input stream: any size (for example, 16 KB)
+ - Buffer for output stream: any size (for example, 16 KB)
+ - LZMA Internal Structures: state_size (16 KB for default settings) 
+ - LZMA dictionary (dictionary size is encoded in LZMA properties header)
+
+1) read LZMA properties (5 bytes) and uncompressed size (8 bytes, little-endian) to header:
+   unsigned char header[LZMA_PROPS_SIZE + 8];
+   ReadFile(inFile, header, sizeof(header)
+
+2) Allocate CLzmaDec structures (state + dictionary) using LZMA properties
+
+  CLzmaDec state;
+  LzmaDec_Constr(&state);
+  res = LzmaDec_Allocate(&state, header, LZMA_PROPS_SIZE, &g_Alloc);
+  if (res != SZ_OK)
+    return res;
+
+3) Init LzmaDec structure before any new LZMA stream. And call LzmaDec_DecodeToBuf in loop
+
+  LzmaDec_Init(&state);
+  for (;;)
+  {
+    ... 
+    int res = LzmaDec_DecodeToBuf(CLzmaDec *p, Byte *dest, SizeT *destLen, 
+        const Byte *src, SizeT *srcLen, ELzmaFinishMode finishMode);
+    ...
+  }
+
+
+4) Free all allocated structures
+  LzmaDec_Free(&state, &g_Alloc);
+
+For full code example, look at C/LzmaUtil/LzmaUtil.c code.
+
+
+How To compress data
+--------------------
+
+Compile files: LzmaEnc.h + LzmaEnc.c + Types.h +
+LzFind.c + LzFind.h + LzFindMt.c + LzFindMt.h + LzHash.h
+
+Memory Requirements:
+  - (dictSize * 11.5 + 6 MB) + state_size
+
+Lzma Encoder can use two memory allocators:
+1) alloc - for small arrays.
+2) allocBig - for big arrays.
+
+For example, you can use Large RAM Pages (2 MB) in allocBig allocator for 
+better compression speed. Note that Windows has bad implementation for 
+Large RAM Pages. 
+It's OK to use same allocator for alloc and allocBig.
+
+
+Single-call Compression with callbacks
+--------------------------------------
+
+Check C/LzmaUtil/LzmaUtil.c as example, 
+
+When to use: file->file decompressing 
+
+1) you must implement callback structures for interfaces:
+ISeqInStream
+ISeqOutStream
+ICompressProgress
+ISzAlloc
+
+static void *SzAlloc(void *p, size_t size) { p = p; return MyAlloc(size); }
+static void SzFree(void *p, void *address) {  p = p; MyFree(address); }
+static ISzAlloc g_Alloc = { SzAlloc, SzFree };
+
+  CFileSeqInStream inStream;
+  CFileSeqOutStream outStream;
+
+  inStream.funcTable.Read = MyRead;
+  inStream.file = inFile;
+  outStream.funcTable.Write = MyWrite;
+  outStream.file = outFile;
+
+
+2) Create CLzmaEncHandle object;
+
+  CLzmaEncHandle enc;
+
+  enc = LzmaEnc_Create(&g_Alloc);
+  if (enc == 0)
+    return SZ_ERROR_MEM;
+
+
+3) initialize CLzmaEncProps properties;
+
+  LzmaEncProps_Init(&props);
+
+  Then you can change some properties in that structure.
+
+4) Send LZMA properties to LZMA Encoder
+
+  res = LzmaEnc_SetProps(enc, &props);
+
+5) Write encoded properties to header
+
+    Byte header[LZMA_PROPS_SIZE + 8];
+    size_t headerSize = LZMA_PROPS_SIZE;
+    UInt64 fileSize;
+    int i;
+
+    res = LzmaEnc_WriteProperties(enc, header, &headerSize);
+    fileSize = MyGetFileLength(inFile);
+    for (i = 0; i < 8; i++)
+      header[headerSize++] = (Byte)(fileSize >> (8 * i));
+    MyWriteFileAndCheck(outFile, header, headerSize)
+
+6) Call encoding function:
+      res = LzmaEnc_Encode(enc, &outStream.funcTable, &inStream.funcTable, 
+        NULL, &g_Alloc, &g_Alloc);
+
+7) Destroy LZMA Encoder Object
+  LzmaEnc_Destroy(enc, &g_Alloc, &g_Alloc);
+
+
+If callback function return some error code, LzmaEnc_Encode also returns that code
+or it can return the code like SZ_ERROR_READ, SZ_ERROR_WRITE or SZ_ERROR_PROGRESS.
+
+
+Single-call RAM->RAM Compression
+--------------------------------
+
+Single-call RAM->RAM Compression is similar to Compression with callbacks,
+but you provide pointers to buffers instead of pointers to stream callbacks:
+
+HRes LzmaEncode(Byte *dest, SizeT *destLen, const Byte *src, SizeT srcLen,
+    CLzmaEncProps *props, Byte *propsEncoded, SizeT *propsSize, int writeEndMark, 
+    ICompressProgress *progress, ISzAlloc *alloc, ISzAlloc *allocBig);
+
+Return code:
+  SZ_OK               - OK
+  SZ_ERROR_MEM        - Memory allocation error 
+  SZ_ERROR_PARAM      - Incorrect paramater
+  SZ_ERROR_OUTPUT_EOF - output buffer overflow
+  SZ_ERROR_THREAD     - errors in multithreading functions (only for Mt version)
+
+
+
+Defines
+-------
+
+_LZMA_SIZE_OPT - Enable some optimizations in LZMA Decoder to get smaller executable code.
+
+_LZMA_PROB32   - It can increase the speed on some 32-bit CPUs, but memory usage for 
+                 some structures will be doubled in that case.
+
+_LZMA_UINT32_IS_ULONG  - Define it if int is 16-bit on your compiler and long is 32-bit.
+
+_LZMA_NO_SYSTEM_SIZE_T  - Define it if you don't want to use size_t type.
+
+
+_7ZIP_PPMD_SUPPPORT - Define it if you don't want to support PPMD method in AMSI-C .7z decoder.
+
+
+C++ LZMA Encoder/Decoder 
+~~~~~~~~~~~~~~~~~~~~~~~~
+C++ LZMA code use COM-like interfaces. So if you want to use it, 
+you can study basics of COM/OLE.
+C++ LZMA code is just wrapper over ANSI-C code.
+
+
+C++ Notes
+~~~~~~~~~~~~~~~~~~~~~~~~
+If you use some C++ code folders in 7-Zip (for example, C++ code for .7z handling),
+you must check that you correctly work with "new" operator.
+7-Zip can be compiled with MSVC 6.0 that doesn't throw "exception" from "new" operator.
+So 7-Zip uses "CPP\Common\NewHandler.cpp" that redefines "new" operator:
+operator new(size_t size)
+{
+  void *p = ::malloc(size);
+  if (p == 0)
+    throw CNewException();
+  return p;
+}
+If you use MSCV that throws exception for "new" operator, you can compile without 
+"NewHandler.cpp". So standard exception will be used. Actually some code of 
+7-Zip catches any exception in internal code and converts it to HRESULT code.
+So you don't need to catch CNewException, if you call COM interfaces of 7-Zip.

+
+
+License Info
+------------
+
+7-Zip is free software distributed under the GNU LGPL 
+(except for unRar code).
+read License.txt for more infomation about license.
+
+Notes about unRAR license:
+
+Please check main restriction from unRar license:
+
+   2. The unRAR sources may be used in any software to handle RAR
+      archives without limitations free of charge, but cannot be used
+      to re-create the RAR compression algorithm, which is proprietary.
+      Distribution of modified unRAR sources in separate form or as a
+      part of other software is permitted, provided that it is clearly
+      stated in the documentation and source comments that the code may
+      not be used to develop a RAR (WinRAR) compatible archiver.
+
+In brief it means:
+1) You can compile and use compiled files under GNU LGPL rules, since 
+   unRAR license almost has no restrictions for compiled files.
+   You can link these compiled files to LGPL programs.
+2) You can fix bugs in source code and use compiled fixed version.
+3) You can not use unRAR sources to re-create the RAR compression algorithm.
+
+
+LZMA SDK
+--------
+
+Also this package contains files from LZMA SDK
+you can download LZMA SDK from this page:
+http://www.7-zip.org/sdk.html
+read about addtional licenses for LZMA SDK in file
+DOC/lzma.txt
+
+
+How to compile
+--------------
+To compile sources you need Visual C++ 6.0.
+For compiling some files you also need 
+new Platform SDK from Microsoft' Site:
+http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm
+or
+http://www.microsoft.com/msdownload/platformsdk/sdkupdate/XPSP2FULLInstall.htm
+or
+http://www.microsoft.com/msdownload/platformsdk/sdkupdate/
+
+If you use MSVC6, specify SDK directories at top of directories lists:
+Tools / Options / Directories
+  - Include files
+  - Library files
+
+
+To compile 7-Zip for AMD64 and IA64 you need:
+  Windows Server 2003 SP1 Platform SDK from microsoft.com
+
+Also you need Microsoft Macro Assembler:
+  - ml.exe for x86 
+  - ml64.exe for AMD64
+You can use ml.exe from Windows SDK for Windows Vista or some other version.
+
+
+Compiling under Unix/Linux
+--------------------------
+Check this site for Posix/Linux version:
+http://sourceforge.net/projects/p7zip/
+
+
+Notes:
+------
+7-Zip consists of COM modules (DLL files).
+But 7-Zip doesn't use standard COM interfaces for creating objects.
+Look at
+7zip\UI\Client7z folder for example of using DLL files of 7-Zip. 
+Some DLL files can use other DLL files from 7-Zip.
+If you don't like it, you must use standalone version of DLL.
+To compile standalone version of DLL you must include all used parts
+to project and define some defs. 
+For example, 7zip\Bundles\Format7z is a standalone version  of 7z.dll 
+that works with 7z format. So you can use such DLL in your project 
+without additional DLL files.

+                  GNU LIBRARY GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+                  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of

+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the

+/*!
+   \class KDGenericFactory
+   \ingroup core
+   \brief Template based generic factory implementation
+   \since_c 2.1
+
+   (The exception safety of this class has not been evaluated yet.)
+
+   KDGenericFactory is an implemention of of the factory pattern. It can be used to
+   "produce" instances of different classes having a common superclass 
+   T_Product. The user of the
+   factory registers those producable classes in the factory by using an identifier
+   (T_Identifier, defaulting to QString). That identifer can then be used to
+   produce as many instances of the registered product as he wants.
+
+   The advanced user can even choose the type of the map the factory is using to store its
+   FactoryFunctions by passing a T_Map template parameter. It defaults to QHash. KDGenericFactory
+   expects it to be a template class accepting T_Identifier and FactoryFunction as parameters.
+   Additionally it needs to provide:
+
+   \li\link QHash::const_iterator a nested %const_iterator \endlink typedef for an iterator type that when dereferenced has type ((const) reference to) FactoryFunction (Qt convention),
+   \li\link QHash::insert %insert( T_Identifier, FactoryFunction ) \endlink, which must overwrite any existing entries with the same identifier.
+   \li\link QHash::find %find( T_Identifier ) \endlink, 
+   \li\link QHash::end %end() \endlink,
+   \li\link QHash::size %size() \endlink, 
+   \li\link QHash::remove %remove( T_Identifier ) \endlink, and 
+   \li\link QHash::keys %keys ) \endlink, returning a QList<T_Identifier>.
+
+   The only two class templates that currently match this concept are
+   QHash and QMap. QMultiHash and QMulitMap do not work, since they
+   violate the requirement on insert() above, and std::map and
+   std::unordered_map do not match because they don't have keys() and
+   because a dereferenced iterator has type
+   std::pair<const T_Identifier,FactoryFunction>
+   instead of just FactoryFunction.
+
+   \section general-use General Use
+    
+   The following example shows how the general use case of KDGenericFactory looks like:
+
+   \code
+
+   class Fruit
+   {
+   };
+
+   class Apple : public Fruit
+   {
+   };
+
+   class Pear : public Fruit
+   {
+   };
+
+   int main()
+   {
+       // creates a common fruit "factory"
+       KDGenericFactory< Fruit > fruitPlantation;
+       // registers the product "Apple"
+       fruitPlantation.registerProduct< Apple >( "Apple" );
+       // registers the product "Pear"
+       fruitPlantation.registerProduct< Pear >( "Pear" );
+
+       // lets create some stuff - here comes our tasty apple:
+       Fruit* myApple = fruitPlantation.create( "Apple" );
+       
+       // and a pear, please:
+       Fruit* myPear = fruitPlantation.create( "Pear" );
+       
+       // ohh - that doesn't work, returns a null pointer:
+       Fruit* myCherry = fruitPlantation.create( "Cherry" );
+   }
+
+   \endcode

+   "KD Updater" is a library from KDAB that helps in enabling automatic updates for your applications.
+   All classes belonging to the "KD Updater" library are defined in the \ref KDUpdater namespace.
+
+   TODO: this comes from the former mainpage:
+KD Updater is a tool to automatically detect, retrieve, install and activate updates to software
+applications and libraries. It is intended to be used with Qt based applications, and developed
+against the Qt 4 series. It is a library that users link to their application. It uses only accepted
+standard protocols, and does not require any other 3rd party libraries that are not shipped with
+Qt.
+
+KD Updater is generic in that it is not developed for one specific application. The first version is
+experimental. If it proves successful and useful, it will be integrated into KDAB's KD Tools
+package. It is part of KDAB's strategy to provide functionality missing in Qt that is required for
+medium-to-large scale software systems.

+   \class KDUpdater::PackagesInfo kdupdaterpackagesinfo.h KDUpdaterPackagesInfo
+   \brief Provides access to information about packages installed on the application side.
+
+   This class parses the XML package file specified via the setFileName() method and
+   provides access to the the information defined within the package file through an
+   easy to use API. You can:
+   \li get application name via the \ref applicationName() method
+   \li get application version via the \ref applicationVersion() method
+   \li get information about the number of packages installed and their meta-data via the
+   \ref packageInfoCount() and \ref packageInfo() methods.
+
+   Instances of this class cannot be created. Each instance of \ref KDUpdater::Application
+   has one instance of this class associated with it. You can fetch a pointer to an instance
+   of this class for an application via the \ref KDUpdater::Application::packagesInfo()
+   method.

+   An update source is a repository that contains updates applicable for the application.
+   Applications can download updates from the update source and install them locally.
+
+   Each application can have one or more update sources from which it can download updates.
+   Information about update source is stored in a file called UpdateSources.xml. This class helps
+   access and modify the UpdateSources.xml file.
+
+   The complete file name of the UpdateSources.xml file can be specified via the \ref setFileName()
+   method. The class then parses the XML file and makes available information contained in
+   that XML file through an easy to use API. You can
+
+   \li Get update sources information via the \ref updateSourceInfoCount() and \ref updateSourceInfo()
+   methods.
+   \li You can add/remove/change update source information via the \ref addUpdateSourceInfo(),
+   \ref removeUpdateSource(), \ref setUpdateSourceAt() methods.
+
+   The class emits appropriate signals to inform listeners about changes in the update application.

+%1.(maybe it is broken or removed)
+It tried to patch the Qt binaries, but all other files in Qt are unpatched.
+This could result in a broken Qt version.
+Sometimes it helps to restart the installer with a switched off antivirus software.</source>
+        <translation>Der Installer konnte den ursprünglichen Pfad aus %1
+nicht lesen (möglicherweise ist es beschädigt oder entfernt).
+Er hat versucht, die Qt Binärdateien trotzdem zu patchen, aber alle anderen
+Dateien im Qt sind ungepatcht. Das kann zu einer beschädigten Qt Version führen.
+Eventuell hilft es, einen laufenden Virenscanner auszuschalten und den Installer erneut zu starten.</translation>
