-      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
-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.

   - Compiled file->file LZMA compressing/decompressing program for Windows system
 
-ANSI-C LZMA decompression code was ported from original C++ sources to C.
-Also it was simplified and optimized for code size.
-But it is fully compatible with LZMA from 7-Zip.

-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.
+To compile C++ version of file->file LZMA encoding, go to directory

 In some UNIX/Linux versions you must compile LZMA with static libraries.
-To compile with static libraries, change string in makefile
-LIB = -lm

 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)
+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.

-allocate memory and send it to LZMA.
-

+larger than 200-400 bytes.
+
+LZMA Decoder uses dictionary buffer and internal state structure.

+  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 5 interfaces:
+LZMA Decoder (ANSI-C version) now supports 2 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)
+2) Multi-call State Decompressing (zlib-like interface)
 
-3) Decode properties:
+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 };
 
-  CLzmaDecoderState state;  /* it's 24-140 bytes structure, if int is 32-bit */
+You can use p = p; operator to disable compiler warnings.
 
-  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.

+
+  You can use multiple checks to test data integrity after full decompression:

-  } CBuffer;
+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)
 
-  int LzmaReadCompressed(void *object, const unsigned char **buffer, SizeT *size)
+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 (;;)
   {
-    CBuffer *bo = (CBuffer *)object;
-    *buffer = bo->Buffer;
-    *size = MyReadFile(bo->File, bo->Buffer, kInBufferSize);
-    return LZMA_RESULT_OK;
+    ...
+    int res = LzmaDec_DecodeToBuf(CLzmaDec *p, Byte *dest, SizeT *destLen,
+	const Byte *src, SizeT *srcLen, ELzmaFinishMode finishMode);
+    ...

-  CBuffer g_InBuffer;
 
-  g_InBuffer.File = inFile;
-  g_InBuffer.InCallback.Read = LzmaReadCompressed;
-  int res = LzmaDecode(&state,
-      &g_InBuffer.InCallback,
-      outStream, outSize, &outProcessed);
+4) Free all allocated structures
+  LzmaDec_Free(&state, &g_Alloc);

+How To compress data
+--------------------
 
+Compile files: LzmaEnc.h + LzmaEnc.c + Types.h +
+LzFind.c + LzFind.h + LzFindMt.c + LzFindMt.h + LzHash.h
 
-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)
+  - (dictSize * 11.5 + 6 MB) + state_size
 
-Interface:
+Lzma Encoder can use two memory allocators:
+1) alloc - for small arrays.
+2) allocBig - for big arrays.
 
-  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+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.
 
-  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.
+Single-call Compression with callbacks
+--------------------------------------
 
+Check C/LzmaUtil/LzmaUtil.c as example,
 
-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)
+When to use: file->file decompressing
 
-Interface:
+1) you must implement callback structures for interfaces:
+ISeqInStream
+ISeqOutStream
+ICompressProgress
+ISzAlloc
 
-  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+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 };
 
-  LzmaDecoderInit(&state);
-  do
-  {
-    LzmaDecode(&state,
-      &bo.InCallback,
-      g_OutBuffer, outAvail, &outProcessed);
-  }
-  while you need more bytes
+  CFileSeqInStream inStream;
+  CFileSeqOutStream outStream;
 
-  see LzmaTest.c for more details:
+  inStream.funcTable.Read = MyRead;
+  inStream.file = inFile;
+  outStream.funcTable.Write = MyWrite;
+  outStream.file = outFile;
 
 
-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)
+2) Create CLzmaEncHandle object;
 
-Interface:
+  CLzmaEncHandle enc;
 
-  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+  enc = LzmaEnc_Create(&g_Alloc);
+  if (enc == 0)
+    return SZ_ERROR_MEM;
 
 
-  LzmaDecoderInit(&state);
-  do
-  {
-    res = LzmaDecode(&state,
-      inBuffer, inAvail, &inProcessed,
-      g_OutBuffer, outAvail, &outProcessed,
-      finishDecoding);
-    inAvail -= inProcessed;
-    inBuffer += inProcessed;
-  }
-  while you need more bytes
+3) initialize CLzmaEncProps properties;
 
-  see LzmaStateTest.c for more details:
+  LzmaEncProps_Init(&props);
 
+  Then you can change some properties in that structure.
 
-6) Free all allocated blocks
+4) Send LZMA properties to LZMA Encoder
 
+  res = LzmaEnc_SetProps(enc, &props);
 
-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.
+5) Write encoded properties to header
 
+    Byte header[LZMA_PROPS_SIZE + 8];
+    size_t headerSize = LZMA_PROPS_SIZE;
+    UInt64 fileSize;
+    int i;
 
-EXIT codes
------------
+    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)
 
-LZMA decoder can return one of the following codes:
+6) Call encoding function:
+      res = LzmaEnc_Encode(enc, &outStream.funcTable, &inStream.funcTable,
+        NULL, &g_Alloc, &g_Alloc);
 
-#define LZMA_RESULT_OK 0
-#define LZMA_RESULT_DATA_ERROR 1
+7) Destroy LZMA Encoder Object
+  LzmaEnc_Destroy(enc, &g_Alloc, &g_Alloc);
 
-If you use callback function for input data and you return some
-error code, LZMA Decoder also returns that code.
 
+If callback function return some error code, LzmaEnc_Encode also returns that code.
 
 
-LZMA Defines
-------------
+Single-call RAM->RAM Compression
+--------------------------------
 
-_LZMA_IN_CB    - Use callback for input data
+Single-call RAM->RAM Compression is similar to Compression with callbacks,
+but you provide pointers to buffers instead of pointers to stream callbacks:
 
-_LZMA_OUT_READ - Use read function for output data
+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);
 
-_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
+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_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
+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.
 
-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.
 
+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.
