+It's an example for LZMA + x86 Filter use.
+You can use .lzma86 extension, if you write that stream to file.
+.lzma86 header adds one additional byte to standard .lzma header.
+.lzma86 header (14 bytes):
+  Offset Size  Description
+    0     1    = 0 - no filter,
+               = 1 - x86 filter
+    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)
