+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 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.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, 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 software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, 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 redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+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 give any other recipients of the Program a copy of this License
+along with the Program.
+
+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 Program or any portion
+of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+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 Program, 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 Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) 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; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, 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 executable. 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.
+
+If distribution of executable or 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 counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program 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.
+
+ 5. 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 Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program 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.
+
+ 7. 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 Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program 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 Program.
+
+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.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program 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.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the 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 Program
+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 Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, 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
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), 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 Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. 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 program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program 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 General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; 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.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+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 (2.30 Beta 25)
+-----------------------------------
+
+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.
+
+Archive structure
+~~~~~~~~~~~~~~~~~
+SignatureHeader
+[PackedStreams]
+[PackedStreamsForHeaders]
+[
+ Header
+ or
+ {
+ Packed Header
+ HeaderInfo
+ }
+]
+
+
+
+Header structure
+~~~~~~~~~~~~~~~~
+{
+ ArchiveProperties
+ AdditionalStreams
+ {

+ NumPackStreams
+ Sizes[NumPackStreams]
+ CRCs[NumPackStreams]
+ }
+ CodersInfo

+
+
+
+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
+ 11111111 BYTE y[8] : y

+ 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.

+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.
+
+
+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)
+
+
+
+LZMA 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.
+
+
+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.

+7-Zip method IDs (4.65)
+-----------------------
+
+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.

+7z ANSI-C Decoder 4.23
+----------------------
+
+7z ANSI-C Decoder 4.23 Copyright (C) 1999-2005 Igor Pavlov
+
+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.
+

+
+
+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", and "CRC" information for each file in archive.
+ - It supports only LZMA and Copy (no compression) methods.
+ - 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
+----------------------
+
+.7z Decoder can be compiled in one of two modes:
+
+1) Default mode. In that mode 7z Decoder will read full compressed
+ block to RAM before decompressing.
+
+2) Mode with defined _LZMA_IN_CB. In that mode 7z Decoder can read
+ compressed block by parts. And you can specify desired buffer size.
+ So memory requirements can be reduced. But decompressing speed will
+ be 5-10% lower and code size is slightly larger.
+
+
+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 ISzInStream interface */
+ CArchiveDatabaseEx db; /* 7z archive database structure */
+ ISzAlloc allocImp; /* memory functions for main pool */
+ ISzAlloc allocTempImp; /* memory functions for temporary pool */
+
+2) call InitCrcTable(); function to initialize CRC structures.
+
+3) call SzArDbExInit(&db); function to initialize db structures.
+
+4) call SzArchiveOpen(inStream, &db, &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.
+SzArchiveOpen function allocates and frees temporary structures by "allocTemp" functions.
+
+5) List items or Extract items
+
+ Listing code:
+ ~~~~~~~~~~~~~
+ {
+ UInt32 i;
+ for (i = 0; i < db.Database.NumFiles; i++)
+ {
+ CFileItem *f = db.Database.Files + i;
+ printf("%10d %s\n", (int)f->Size, f->Name);
+ }
+ }
+
+ Extracting code:
+ ~~~~~~~~~~~~~~~~
+
+ SZ_RESULT SzExtract(
+ ISzInStream *inStream,
+ CArchiveDatabaseEx *db,
+ 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 SzArDbExFree(&db, allocImp.Free) to free allocated items in "db".
+
+
+
+
+Memory requirements for .7z decoding
+------------------------------------
+
+Memory usage for Archive opening:
+ - Temporary pool:
+ - Memory for compressed .7z headers (if _LZMA_IN_CB is not defined)
+ - 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)
+ - Some file information (4 bytes)
+ - File Name (variable length) + pointer + allocation structures
+
+Memory usage for archive Decompressing:
+ - Temporary pool:
+ - Memory for compressed solid block (if _LZMA_IN_CB is not defined)
+ - Memory for LZMA decompressing structures
+ - Main pool:
+ - Memory for decompressed solid block
+
+
+If _LZMA_IN_CB is defined, 7z Decoder will not allocate memory for
+compressed blocks. Instead of this, you must allocate buffer with desired
+size before calling 7z Decoder. Use 7zMain.c as example.
+
+
+
+EXIT codes
+-----------
+
+7z Decoder functions can return one of the following codes:
+
+#define SZ_OK (0)
+#define SZE_DATA_ERROR (1)
+#define SZE_OUTOFMEMORY (2)
+#define SZE_CRC_ERROR (3)
+
+#define SZE_NOTIMPL (4)
+#define SZE_FAIL (5)
+
+#define SZE_ARCHIVE_ERROR (6)
+
+
+
+LZMA Defines
+------------
+
+_LZMA_IN_CB - Use special callback mode for input stream to reduce memory requirements
+
+_SZ_FILE_SIZE_64 - define it if you need support for files larger than 4 GB
+_SZ_NO_INT_64 - define it if your compiler doesn't support long long int
+
+_LZMA_PROB32 - it can increase LZMA decompressing speed on some 32-bit CPUs.
+
+_SZ_ONE_DIRECTORY - define it if you want to locate all source files to one directory
+_SZ_ALLOC_DEBUG - define it if you want to debug alloc/free operations to stderr.
