+
+LZMA SDK   Copyright (C) 1999-2007 Igor Pavlov
+
+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.

+But it is fully compatible with LZMA from 7-Zip.
+
+
+UNIX/Linux version
+------------------
+To compile C++ version of file->file LZMA, go to directory
+C/7zip/Compress/LZMA_Alone
+and type "make" or "make clean all" to recompile all.
+
+In some UNIX/Linux versions you must compile LZMA with static libraries.
+To compile with static libraries, change string in makefile
+LIB = -lm
+to string
+LIB = -lm -static

+C/C++ source code of LZMA SDK is part of 7-Zip project.
+
+You can find ANSI-C LZMA decompressing code at folder
+  C/7zip/Compress/Lzma
+7-Zip doesn't use that ANSI-C LZMA code and that code was developed
+specially for this SDK. And files from C/7zip/Compress/Lzma do not need
+files from other directories of SDK for compiling.
+
+7-Zip source code can be downloaded from 7-Zip's SourceForge page:
+
+  http://sourceforge.net/projects/sevenzip/
+
+
+LZMA features
+-------------
+  - Variable dictionary size (up to 1 GB)
+  - Estimated compressing speed: about 1 MB/s on 1 GHz CPU
+  - Estimated decompressing speed:
+      - 8-12 MB/s on 1 GHz Intel Pentium 3 or AMD Athlon
+      - 500-1000 KB/s on 100 MHz ARM, MIPS, PowerPC or other simple RISC
+  - Small memory requirements for decompressing (8-32 KB + DictionarySize)
+  - Small code size for decompressing: 2-8 KB (depending from
+    speed optimizations)
+
+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 to 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
+
+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 AMD Athlon 64 X2 CPU
+     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. Also you
+     can change 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 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, ...).
+
+
+Using Filters
+-------------
+You can increase compression ratio for some data types, using
+special filters before compressing. For example, it's possible to
+increase compression ratio on 5-10% for code for those CPU ISAs:
+x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.
+
+You can find C/C++ source code of such filters in folder "7zip/Compress/Branch"
+
+You can check 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=bc_arm -m1=lzma
+
+With filter for big-endian ARM code (using additional Swap4 filter):
+  7z a a3.7z a.bin -m0=swap4 -m1=bc_arm -m2=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. Source code of these CALL filters is pretty simple
+(about 20 lines of C++), so you can convert it from C++ version yourself.
+
+For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.
+
+
+LZMA compressed file format
+---------------------------
+Offset Size Description
+  0	1   Special LZMA properties for compressed data
+  1	4   Dictionary size (little endian)
+  5	8   Uncompressed size (little endian). -1 means unknown size
+ 13	    Compressed data
+
+
+ANSI-C LZMA Decoder
+~~~~~~~~~~~~~~~~~~~
+
+To compile ANSI-C LZMA Decoder you can use one of the following files sets:
+1) LzmaDecode.h + LzmaDecode.c + LzmaTest.c  (fastest version)
+2) LzmaDecode.h + LzmaDecodeSize.c + LzmaTest.c  (old size-optimized version)
+3) LzmaStateDecode.h + LzmaStateDecode.c + LzmaStateTest.c  (zlib-like interface)
+
+
+Memory requirements for LZMA decoding
+-------------------------------------
+
+LZMA decoder doesn't allocate memory itself, so you must
+allocate memory and send it to LZMA.
+
+Stack usage of LZMA decoding function for local variables is not
+larger than 200 bytes.
+
+How To decompress data
+----------------------
+
+LZMA Decoder (ANSI-C version) now supports 5 interfaces:
+1) Single-call Decompressing
+2) Single-call Decompressing with input stream callback
+3) Multi-call Decompressing with output buffer
+4) Multi-call Decompressing with input callback and output buffer
+5) Multi-call State Decompressing (zlib-like interface)
+
+Variant-5 is similar to Variant-4, but Variant-5 doesn't use callback functions.
+
+Decompressing steps
+-------------------
+
+1) read LZMA properties (5 bytes):
+   unsigned char properties[LZMA_PROPERTIES_SIZE];
+
+2) read uncompressed size (8 bytes, little-endian)
+
+3) Decode properties:
+
+  CLzmaDecoderState state;  /* it's 24-140 bytes structure, if int is 32-bit */
+
+  if (LzmaDecodeProperties(&state.Properties, properties, LZMA_PROPERTIES_SIZE) != LZMA_RESULT_OK)
+    return PrintError(rs, "Incorrect stream properties");
+
+4) Allocate memory block for internal Structures:
+
+  state.Probs = (CProb *)malloc(LzmaGetNumProbs(&state.Properties) * sizeof(CProb));
+  if (state.Probs == 0)
+    return PrintError(rs, kCantAllocateMessage);
+
+  LZMA decoder uses array of CProb variables as internal structure.
+  By default, CProb is unsigned_short. But you can define _LZMA_PROB32 to make
+  it unsigned_int. It can increase speed on some 32-bit CPUs, but memory
+  usage will be doubled in that case.
+
+
+5) Main Decompressing
+
+You must use one of the following interfaces:
+
+5.1 Single-call Decompressing

+  {
+    CBuffer *bo = (CBuffer *)object;
+    *buffer = bo->Buffer;
+    *size = MyReadFile(bo->File, bo->Buffer, kInBufferSize);
+    return LZMA_RESULT_OK;
+  }
+
+  CBuffer g_InBuffer;
+
+  g_InBuffer.File = inFile;
+  g_InBuffer.InCallback.Read = LzmaReadCompressed;
+  int res = LzmaDecode(&state,
+      &g_InBuffer.InCallback,
+      outStream, outSize, &outProcessed);
+
+
+5.3 Multi-call decompressing with output buffer
+-----------------------------------------------
+When to use: RAM->File decompressing
+Compile files: LzmaDecode.h, LzmaDecode.c
+Compile defines: _LZMA_OUT_READ
+Memory Requirements:
+ - Input buffer: compressed size
+ - Buffer for output stream: any size (for example, 16 KB)
+ - LZMA Internal Structures (~16 KB for default settings)
+ - LZMA dictionary (dictionary size is encoded in stream properties)
+
+Interface:
+
+  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+
+  LzmaDecoderInit(&state);
+  do
+  {
+    LzmaDecode(&state,
+      inBuffer, inAvail, &inProcessed,
+      g_OutBuffer, outAvail, &outProcessed);
+    inAvail -= inProcessed;
+    inBuffer += inProcessed;
+  }
+  while you need more bytes
+
+  see LzmaTest.c for more details.
+
+
+5.4 Multi-call decompressing with input callback and output buffer
+------------------------------------------------------------------
+When to use: File->File decompressing
+Compile files: LzmaDecode.h, LzmaDecode.c
+Compile defines: _LZMA_IN_CB, _LZMA_OUT_READ
+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 (~16 KB for default settings)
+ - LZMA dictionary (dictionary size is encoded in stream properties)
+
+Interface:
+
+  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+
+  LzmaDecoderInit(&state);
+  do
+  {
+    LzmaDecode(&state,
+      &bo.InCallback,
+      g_OutBuffer, outAvail, &outProcessed);
+  }
+  while you need more bytes
+
+  see LzmaTest.c for more details:
+
+
+5.5 Multi-call State Decompressing (zlib-like interface)
+------------------------------------------------------------------
+When to use: file->file decompressing
+Compile files: LzmaStateDecode.h, LzmaStateDecode.c
+Compile defines:
+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 (~16 KB for default settings)
+ - LZMA dictionary (dictionary size is encoded in stream properties)
+
+Interface:
+
+  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+
+
+  LzmaDecoderInit(&state);
+  do
+  {
+    res = LzmaDecode(&state,
+      inBuffer, inAvail, &inProcessed,
+      g_OutBuffer, outAvail, &outProcessed,
+      finishDecoding);
+    inAvail -= inProcessed;
+    inBuffer += inProcessed;
+  }
+  while you need more bytes
+
+  see LzmaStateTest.c for more details:
+
+
+6) Free all allocated blocks
+
+
+Note
+----
+LzmaDecodeSize.c is size-optimized version of LzmaDecode.c.
+But compiled code of LzmaDecodeSize.c can be larger than
+compiled code of LzmaDecode.c. So it's better to use
+LzmaDecode.c in most cases.
+
+
+EXIT codes
+-----------
+
+LZMA decoder can return one of the following codes:
+
+#define LZMA_RESULT_OK 0
+#define LZMA_RESULT_DATA_ERROR 1
+
+If you use callback function for input data and you return some
+error code, LZMA Decoder also returns that code.
+
+
+
+LZMA Defines
+------------
+
+_LZMA_IN_CB    - Use callback for input data
+
+_LZMA_OUT_READ - Use read function for output data
+
+_LZMA_LOC_OPT  - Enable local speed optimizations inside code.
+		 _LZMA_LOC_OPT is only for LzmaDecodeSize.c (size-optimized version).
+		 _LZMA_LOC_OPT doesn't affect LzmaDecode.c (speed-optimized version)
+		 and LzmaStateDecode.c
+
+_LZMA_PROB32   - It can increase speed on some 32-bit CPUs,
+		 but memory usage 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_SYSTEM_SIZE_T  - Define it if you want to use system's size_t.
+		       You can use it to enable 64-bit sizes supporting
+
+
+
+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.
+
+By default, LZMA Encoder contains all Match Finders.
+But for compressing it's enough to have just one of them.
+So for reducing size of compressing code you can define:
+  #define COMPRESS_MF_BT
+  #define COMPRESS_MF_BT4
+and it will use only bt4 match finder.
+
+
