bulk copy of latest physfs to our misc/libphysfs since this seems to fix an off-by-1 error reliably hit in readln read of 1 byte probably introduced in the addition of the buffered read. Whether this is excessive or whether libphysfs should even be maintained by us is another matter. But at least we shouldn't crash

+7z ANSI-C Decoder 4.48
+----------------------
+
+7z ANSI-C Decoder 4.48 Copyright (C) 1999-2006 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.
+
+
+LICENSE

+
+Files

+
+7zAlloc.*    - Allocate and Free
+7zBuffer.*   - Buffer structure

+7zTypes.h    - Base types and constants
+
+
+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
+----------------------
+
+.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)
+         - LastWriteTime (8 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
+     - Memory for temprorary buffers, if BCJ2 fileter is used. Usually these 
+       temprorary buffers can be about 15% of solid block size. 
+  
+
+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_32  - define it if you need only support for files smaller than 4 GB
+_SZ_NO_INT_64     - define it if your compiler doesn't support long long int or __int64.
+
+_LZMA_PROB32      - it can increase LZMA decompressing speed on some 32-bit CPUs.
+
+_SZ_ALLOC_DEBUG   - define it if you want to debug alloc/free operations to stderr.

+      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.
+
+  <signature of Ty Coon>, 1 April 1990

+
+That's all there is to it!

+7-Zip method IDs (4.56)
+-----------------------
+
+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:
+
+    7F ZZ ZZ ZZ ZZ ZZ MM MM 
+
+    7F              - 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.

+
+  4.39 beta      2006-04-14
+  -------------------------
+    - Bug in versions 4.33b:4.38b was fixed:
+      C++ version of LZMA encoder could not correctly compress 
+      files larger than 2 GB with HC4 match finder (-mfhc4).
+      
+
+  4.37 beta      2005-04-06
+  -------------------------
+    - Fixes in C++ code: code could no be compiled if _NO_EXCEPTIONS was defined. 
+
+  
+  4.35 beta      2005-03-02
+  -------------------------
+    - Bug was fixed in C++ version of LZMA Decoder:

+  -------------------------
+    - Small fixes
+
+
+  4.21           2005-06-08
+  -------------------------
+    - Interfaces for ANSI-C LZMA Decoder (LzmaDecode.c) were changed
+    - New additional version of ANSI-C LZMA Decoder with zlib-like interface:
+        - LzmaStateDecode.h
+        - LzmaStateDecode.c
+        - LzmaStateTest.c
+    - ANSI-C LZMA Decoder now can decompress files larger than 4 GB
+
+  
+  4.17           2005-04-18
+  -------------------------
+    - New example for RAM->RAM compressing/decompressing: 
+      LZMA + BCJ (filter for x86 code):
+        - LzmaRam.h
+        - LzmaRam.cpp
+        - LzmaRamDecode.h
+        - LzmaRamDecode.c

+       If _LZMA_OUT_READ was defined, and if encoded stream was corrupted,
+       decoder could access memory outside of allocated range.
+    - Speed optimization of ANSI-C LZMA Decoder (now it's about 20% faster).
+      Old version of LZMA Decoder now is in file LzmaDecodeSize.c.

+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.

+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.

+
+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
+-----------------------------
+When to use: RAM->RAM decompressing
+Compile files: LzmaDecode.h, LzmaDecode.c
+Compile defines: no defines
+Memory Requirements:
+  - Input buffer: compressed size
+  - Output buffer: uncompressed size
+  - LZMA Internal Structures (~16 KB for default settings) 
+
+Interface:
+  int res = LzmaDecode(&state, 
+      inStream, compressedSize, &inProcessed,
+      outStream, outSize, &outProcessed);
+
+
+5.2 Single-call Decompressing with input stream callback
+--------------------------------------------------------
+When to use: File->RAM or Flash->RAM decompressing.
+Compile files: LzmaDecode.h, LzmaDecode.c
+Compile defines: _LZMA_IN_CB
+Memory Requirements:
+  - Buffer for input stream: any size (for example, 16 KB)
+  - Output buffer: uncompressed size
+  - LZMA Internal Structures (~16 KB for default settings) 
+
+Interface:
+  typedef struct _CBuffer
+  {
+    ILzmaInCallback InCallback;
+    FILE *File;
+    unsigned char Buffer[kInBufferSize];
+  } CBuffer;
+
+  int LzmaReadCompressed(void *object, const unsigned char **buffer, SizeT *size)
+  {

+-----------------------------------------------
+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:

+
+
+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.

+/**
+ * \struct PHYSFS_Archiver
+ * \brief Abstract interface to provide support for user-defined archives.
+ *
+ * \warning This is advanced, hardcore stuff. You don't need this unless you
+ *          really know what you're doing. Most apps will not need this.
+ *
+ * Historically, PhysicsFS provided a means to mount various archive file
+ *  formats, and physical directories in the native filesystem. However,
+ *  applications have been limited to the file formats provided by the
+ *  library. This interface allows an application to provide their own
+ *  archive file types.
+ *
+ * Conceptually, a PHYSFS_Archiver provides directory entries, while
+ *  PHYSFS_Io provides data streams for those directory entries. The most
+ *  obvious use of PHYSFS_Archiver is to provide support for an archive
+ *  file type that isn't provided by PhysicsFS directly: perhaps some
+ *  proprietary format that only your application needs to understand.
+ *
+ * Internally, all the built-in archive support uses this interface, so the
+ *  best examples for building a PHYSFS_Archiver is the source code to
+ *  PhysicsFS itself.
+ *
+ * An archiver is added to the system with PHYSFS_registerArchiver(), and then
+ *  it will be available for use automatically with PHYSFS_mount(); if a
+ *  given archive can be handled with your archiver, it will be given control
+ *  as appropriate.
+ *
+ * These methods deal with dir handles. You have one instance of your
+ *  archiver, and it generates a unique, opaque handle for each opened
+ *  archive in its openArchive() method. Since the lifetime of an Archiver
+ *  (not an archive) is generally the entire lifetime of the process, and it's
+ *  assumed to be a singleton, we do not provide any instance data for the
+ *  archiver itself; the app can just use some static variables if necessary.
+ *
+ * Symlinks should always be followed (except in stat()); PhysicsFS will
+ *  use the stat() method to check for symlinks and make a judgement on
+ *  whether to continue to call other methods based on that.
+ *
+ * Archivers, when necessary, should set the PhysicsFS error state with
+ *  PHYSFS_setErrorCode() before returning. PhysicsFS will pass these errors
+ *  back to the application unmolested in most cases.
+ *
+ * Thread safety: TO BE DECIDED.  !!! FIXME

+* Windows Runtime support routines for PhysicsFS.
+*
+* Please see the file LICENSE.txt in the source's root directory.
+*
+*  This file is based on "platform_windows.c" by Ryan C. Gordon and Gregory S. Read.
+*  Windows Runtime-specific additions and changes are made by Martin "T-Bone" Ahrnbom. 
+*
+* Instructions for setting up PhysFS in a WinRT Universal 8.1 app in Visual Studio 2013:
+* (hopefully these instructions will be somewhat valid with Windows 10 Apps as well...)
+*
+*  1. In Visual Studio 2013 (or later?), hit File -> New -> Project...
+*  2. On the left, navigate to Templates -> Visual C++ -> Store Apps -> Universal Apps
+*  3. In the middle of the window, select "DLL (Universal Apps)"
+*  4. Near the bottom, give the project a name (like PhysFS-WinRT) and choose a location
+*  5. In the Solution Explorer (to the right typically), delete all .cpp and .h files in
+*     PhysFS-WinRT.Shared except targetver.h.
+*  6. In Windows Explorer, find the "src" folder of the PhysFS source code. Select all files
+* 	  in the folder (ignore the "lzma" folder, we're not including 7Zip support because it's messy to compile).
+*	  Drag and drop all of the source files onto PhysFS-WinRT-Shared in Visual Studio.
+*  7. In Windows Explorer, find the file called "physfs.h". Copy this file into a folder of its own somewhere.
+*	  I suggest naming that folder "include". This will be your "include" folder for any projects using PhysFS.
+*  8. In the Solution Explorer, right click on PhysFS-WinRT.Windows and select Properties. Make sure that "Configuration" is set to 
+*     "All Configurations" and "Platform" is set to "All Platforms" near the top of the window.
+*  9. On the left, select "Precompiled Headers". Change "Precompiled Header" from "Use (/Yu)" to "Not Using Precompiled Headers".
+* 10. On the left, navigate to Configuration Properties -> C/C++ -> Preprocessor. In Preprocessor Definitions, add "_CRT_SECURE_NO_WARNINGS"
+* 11. Hit the OK button.
+* 12. Repeat steps 8-11 but for PhysFS-WinRT.WindowsPhone.
+* 13. In the Solution Explorer, find "platform_winrt.cpp" in PhysFS-WinRT.Shared. Right click on it and select "Properties". 
+* 14. On the left, navigate to Configuration Properties -> C/C++ -> General. On the right, change "Consume Windows Runtime Extensions"
+*	  from "No" to "Yes (/ZW)". Hit "OK".
+* 15. Near the top of the Visual Studio window, select BUILD -> Batch Build... Hit "Select All", and then "Build".
+* 16. Now you have a bunch of .dll and .lib files, as well as an include folder that you can use in your projects!
+* 17. ???
+* 18. Profit!
