    Bink and Smacker were written by me, Jeff Roberts. I had lots of help, but,
    at the end of the day, I wrote them, I documented them, and I decided what 
    they do and what they don't. So, if you hate 'em, then it's my fault. But 
    if you like them, well, that's my fault too... Special thanks to Mitch 
    Soule, John Miles, Casey Muratori, Mike Sartain, Mike Abrash, and my wife,
    Alicia Fukunaga, someone I try to be more like. 

    Mark Engleberg and I did the original research work on Bink. David 
    Lawrence at Blizzard did much of the heavy lifting of porting Bink to 
    MacOS (and he tolerated many questions). Mike Sartain did the port to 
    GameCube and wrote several of the Xbox examples. Mike Sartain also got 
    the PS2 port up and running. Lee Powell, John Miles and Mike Abrash all 
    wrote YUV blitters over the years. David Etherton was also amazingly 
    helpful in getting the PS2 port wrapped up. Jason Dorie had the good idea 
    of using palettes with 3D hardware to do color conversion in hardware on 
    some older platforms. 

    Thanks also to Brian Kearney, Ken Coburn, Chris Hecker, Access Software, 
    Microsoft (both for the nice tools and the tough competition), and all 
    our Bink and Smacker licensees. 

    RAD's automatic documentation system was written by Casey Muratori. 

    Thanks to AMD for their kind support during the development of Bink for
    Windows 64!

    The IJG distribution formerly included code to read and write GIF files.

    support has been removed altogether, and the GIF writer has been simplified

    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.
    
    LZMA2 is a LZMA based compression method. LZMA2 provides better 
    multithreading support for compression than LZMA and some other improvements.
    
    7z is a file format for data compression and file archiving.
    7z is a main file format for 7-Zip compression program (www.7-zip.org).
    7z format supports different compression methods: LZMA, LZMA2 and others.
    7z also supports AES-256 based encryption.
    
    XZ is a file format for data compression that uses LZMA2 compression.
    XZ format provides additional features: SHA/CRC check, filters for

    price.  Our General Public Licenses are designed to make sure that you
    have the freedom to distribute copies of free software (and charge for
    this service if you wish), that you receive source code or can get it
    if you want it, that you can change the software or use pieces of it
    in new free programs; and that you know you can do these things.
    
      To protect your rights, we need to make restrictions that forbid
    anyone to deny you these rights or to ask you to surrender the rights.
    These restrictions translate to certain responsibilities for you if you
    distribute copies of the software, or if you modify it.
    
      For example, if you distribute copies of such a program, whether
    gratis or for a fee, you must give the recipients all the rights that
    you have.  You must make sure that they, too, receive or can get the
    source code.  And you must show them these terms so they know their
    rights.
    
      We protect your rights with two steps: (1) copyright the software,
    and (2) offer you this license which gives you legal permission to
    copy, distribute and/or modify the software.
    
      Also, for each author's protection and ours, we want to make certain
    that everyone understands that there is no warranty for this free
    software.  If the software is modified by someone else and passed on,
    
    we want its recipients to know that what they have is not the original,
    so that any problems introduced by others will not reflect on the
    original authors' reputations.
    
      Finally, any free program is threatened constantly by software
    patents.  We wish to avoid the danger that redistributors of a free
    program will individually obtain patent licenses, in effect making the
    program proprietary.  To prevent this, we have made it clear that any
    patent must be licensed for everyone's free use or not licensed at all.
    
      The precise terms and conditions for copying, distribution and
    modification follow.
    
                        GNU GENERAL PUBLIC LICENSE
       TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    
      0. This License applies to any program or other work which contains
    a notice placed by the copyright holder saying it may be distributed
    under the terms of this General Public License.  The "Program", below,
    refers to any such program or work, and a "work based on the Program"
    means either the Program or any derivative work under copyright law:
    that is to say, a work containing the Program or a portion of it,
    either verbatim or with modifications and/or translated into another
    language.  (Hereinafter, translation is included without limitation in
    the term "modification".)  Each licensee is addressed as "you".
    
    Activities other than copying, distribution and modification are not
    covered by this License; they are outside its scope.  The act of
    running the Program is not restricted, and the output from the Program
    is covered only if its contents constitute a work based on the
    Program (independent of having been made by running the Program).
    Whether that is true depends on what the Program does.
    
    
      1. You may copy and distribute verbatim copies of the Program's
    source code as you receive it, in any medium, provided that you
    conspicuously and appropriately publish on each copy an appropriate
    copyright notice and disclaimer of warranty; keep intact all the
    notices that refer to this License and to the absence of any warranty;
    and give any other recipients of the Program a copy of this License
    along with the Program.
    
    You may charge a fee for the physical act of transferring a copy, and
    you may at your option offer warranty protection in exchange for a fee.
    
    
      2. You may modify your copy or copies of the Program or any portion
    of it, thus forming a work based on the Program, and copy and
    distribute such modifications or work under the terms of Section 1
    above, provided that you also meet all of these conditions:
    
        a) You must cause the modified files to carry prominent notices
        stating that you changed the files and the date of any change.
    
        b) You must cause any work that you distribute or publish, that in
        whole or in part contains or is derived from the Program or any
        part thereof, to be licensed as a whole at no charge to all third
        parties under the terms of this License.
    
        c) If the modified program normally reads commands interactively
        when run, you must cause it, when started running for such
        interactive use in the most ordinary way, to print or display an
        announcement including an appropriate copyright notice and a
        notice that there is no warranty (or else, saying that you provide
        a warranty) and that users may redistribute the program under
        these conditions, and telling the user how to view a copy of this
        License.  (Exception: if the Program itself is interactive but
        does not normally print such an announcement, your work based on
        the Program is not required to print an announcement.)
    
    These requirements apply to the modified work as a whole.  If
    identifiable sections of that work are not derived from the Program,
    and can be reasonably considered independent and separate works in
    themselves, then this License, and its terms, do not apply to those
    sections when you distribute them as separate works.  But when you
    distribute the same sections as part of a whole which is a work based
    on the Program, the distribution of the whole must be on the terms of
    this License, whose permissions for other licensees extend to the
    entire whole, and thus to each and every part regardless of who wrote it.
    
    Thus, it is not the intent of this section to claim rights or contest
    your rights to work written entirely by you; rather, the intent is to
    exercise the right to control the distribution of derivative or
    collective works based on the Program.
    
    In addition, mere aggregation of another work not based on the Program
    with the Program (or with a work based on the Program) on a volume of
    a storage or distribution medium does not bring the other work under
    the scope of this License.
    
    
      3. You may copy and distribute the Program (or a work based on it,
    under Section 2) in object code or executable form under the terms of
    Sections 1 and 2 above provided that you also do one of the following:
    
        a) Accompany it with the complete corresponding machine-readable
        source code, which must be distributed under the terms of Sections
        1 and 2 above on a medium customarily used for software
        interchange; or,
    
        b) Accompany it with a written offer, valid for at least three
        years, to give any third party, for a charge no more than your
        cost of physically performing source distribution, a complete
        machine-readable copy of the corresponding source code, to be
        distributed under the terms of Sections 1 and 2 above on a medium
        customarily used for software interchange; or,
    
        c) Accompany it with the information you received as to the offer
        to distribute corresponding source code.  (This alternative is
        allowed only for noncommercial distribution and only if you
        received the program in object code or executable form with such
        an offer, in accord with Subsection b above.)
    
    The source code for a work means the preferred form of the work for
    making modifications to it.  For an executable work, complete source
    code means all the source code for all modules it contains, plus any
    associated interface definition files, plus the scripts used to
    control compilation and installation of the executable.  However, as
    a special exception, the source code distributed need not include
    anything that is normally distributed (in either source or binary
    form) with the major components (compiler, kernel, and so on) of the
    operating system on which the executable runs, unless that component
    itself accompanies the executable.
    
    If distribution of executable or object code is made by offering
    access to copy from a designated place, then offering equivalent
    access to copy the source code from the same place counts as
    distribution of the source code, even though third parties are not
    compelled to copy the source along with the object code.
    
    
      4. You may not copy, modify, sublicense, or distribute the Program
    except as expressly provided under this License.  Any attempt
    otherwise to copy, modify, sublicense or distribute the Program is
    void, and will automatically terminate your rights under this License.
    However, parties who have received copies, or rights, from you under
    this License will not have their licenses terminated so long as such
    parties remain in full compliance.
    
    
      5. You are not required to accept this License, since you have not
    signed it.  However, nothing else grants you permission to modify or
    distribute the Program or its derivative works.  These actions are
    prohibited by law if you do not accept this License.  Therefore, by
    modifying or distributing the Program (or any work based on the
    Program), you indicate your acceptance of this License to do so, and
    all its terms and conditions for copying, distributing or modifying
    the Program or works based on it.
    
    
      6. Each time you redistribute the Program (or any work based on the
    Program), the recipient automatically receives a license from the
    original licensor to copy, distribute or modify the Program subject to
    these terms and conditions.  You may not impose any further
    restrictions on the recipients' exercise of the rights granted herein.
    You are not responsible for enforcing compliance by third parties to
    this License.
    
    
      7. If, as a consequence of a court judgment or allegation of patent
    infringement or for any other reason (not limited to patent issues),
    conditions are imposed on you (whether by court order, agreement or
    otherwise) that contradict the conditions of this License, they do not
    excuse you from the conditions of this License.  If you cannot
    distribute so as to satisfy simultaneously your obligations under this
    License and any other pertinent obligations, then as a consequence you
    may not distribute the Program at all.  For example, if a patent
    license would not permit royalty-free redistribution of the Program by
    all those who receive copies directly or indirectly through you, then
    the only way you could satisfy both it and this License would be to
    refrain entirely from distribution of the Program.
    
    If any portion of this section is held invalid or unenforceable under
    any particular circumstance, the balance of the section is intended to
    apply and the section as a whole is intended to apply in other
    circumstances.
    
    It is not the purpose of this section to induce you to infringe any
    patents or other property right claims or to contest validity of any
    such claims; this section has the sole purpose of protecting the
    integrity of the free software distribution system, which is
    implemented by public license practices.  Many people have made
    generous contributions to the wide range of software distributed
    through that system in reliance on consistent application of that
    system; it is up to the author/donor to decide if he or she is willing
    to distribute software through any other system and a licensee cannot
    impose that choice.
    
    This section is intended to make thoroughly clear what is believed to
    be a consequence of the rest of this License.
    
    
      8. If the distribution and/or use of the Program is restricted in
    certain countries either by patents or by copyrighted interfaces, the
    original copyright holder who places the Program under this License
    may add an explicit geographical distribution limitation excluding
    those countries, so that distribution is permitted only in or among
    countries not thus excluded.  In such case, this License incorporates
    the limitation as if written in the body of this License.
    
    
      9. The Free Software Foundation may publish revised and/or new
    versions of the General Public License from time to time.  Such new
    versions will be similar in spirit to the present version, but may
    differ in detail to address new problems or concerns.
    
    Each version is given a distinguishing version number.  If the Program
    specifies a version number of this License which applies to it and
    "any later version", you have the option of following the terms and
    conditions either of that version or of any later version published by
    the Free Software Foundation.  If the Program does not specify a
    version number of this License, you may choose any version ever
    published by the Free Software Foundation.
    
      10. If you wish to incorporate parts of the Program into other free
    programs whose distribution conditions are different, write to the
    author to ask for permission.  For software which is copyrighted by the
    Free Software Foundation, write to the Free Software Foundation; we
    sometimes make exceptions for this.  Our decision will be guided by the
    two goals of preserving the free status of all derivatives of our free
    software and of promoting the sharing and reuse of software generally.
    
                                NO WARRANTY
    
      11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
    WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
    
    EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
    OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND,
    EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
    THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS
    WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
    ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
    
      12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
    WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
    AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
    FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
    CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
    PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
    RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
    FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
    SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
    DAMAGES.
    
                         END OF TERMS AND CONDITIONS
    
                How to Apply These Terms to Your New Programs
    
      If you develop a new program, and you want it to be of the greatest
    possible use to the public, the best way to achieve this is to make it
    free software which everyone can redistribute and change under these
    terms.
    
      To do so, attach the following notices to the program.  It is safest
    to attach them to the start of each source file to most effectively
    convey the exclusion of warranty; and each file should have at least
    the "copyright" line and a pointer to where the full notice is found.
    
        <one line to give the program's name and a brief idea of what it
        does.>
        Copyright (C) <year>  <name of author>
    
        This program is free software; you can redistribute it and/or
        modify it under the terms of the GNU General Public License as
        published by     the Free Software Foundation; either version
        2 of the License, or (at your option) any later version.
    
        This program is distributed in the hope that it will be useful,
        but WITHOUT ANY WARRANTY; without even the implied warranty of
        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
        GNU General Public License for more details.
    
        You should have received a copy of the GNU General Public License
        along with this program; if not, write to the Free Software
        Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA
        02110-1301 USA.
    
    Also add information on how to contact you by electronic and paper mail.
    
    If the program is interactive, make it output a short notice like this
    when it starts in an interactive mode:
    
        Gnomovision version 69, Copyright (C) year name of author
        Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
        type 'show w'. This is free software, and you are welcome
        to redistribute it under certain conditions; type 'show c'
        for details.
    
    The hypothetical commands 'show w' and 'show c' should show the
    appropriate parts of the General Public License.  Of course, the
    commands you use may be called something other than 'show w' and
    'show c'; they could even be mouse-clicks or menu items--whatever
    suits your program.
    
    You should also get your employer (if you work as a programmer) or your
    school, if any, to sign a "copyright disclaimer" for the program, if
    necessary.  Here is a sample; alter the names:
    
      Yoyodyne, Inc., hereby disclaims all copyright interest in the
      program 'Gnomovision' (which makes passes at compilers) written
      by James Hacker.

    This General Public License does not permit incorporating your program
    into proprietary programs.  If your program is a subroutine library,
    you may consider it more useful to permit linking proprietary
    applications with the library.  If this is what you want to do, use
    the GNU Lesser General Public License instead of this License.
    
    
    A.4. md5 (Message-Digest Algorithm 5) License
    ----------------------------------------------------------------
    The following software may be included in this product:
    
    md5 (Message-Digest Algorithm 5)
    
     This code implements the MD5 message-digest algorithm.
     The algorithm is due to Ron Rivest.  This code was
     written by Colin Plumb in 1993, no copyright is claimed.
     This code is in the public domain; do with it what you wish.
    
     Equivalent code is available from RSA Data Security, Inc.
     This code has been tested against that, and is equivalent,
     except that you don't need to include two pages of legalese
     with every copy.
    
     The code has been modified by Mikael Ronstroem to handle
     calculating a hash value of a key that is always a multiple
     of 4 bytes long. Word 0 of the calculated 4-word hash value
     is returned as the hash value.
