-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 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

-  Offset Size  Description
-    0     1    = 0 - no filter, pure LZMA
-               = 1 - x86 filter + LZMA
-    1     1    lc, lp and pb in encoded form
-    2     4    dictSize (little endian)
-    6     8    uncompressed size (little endian)
-
-
-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
-
-
-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)

- 
-  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.
-     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.
