Freetype Project License or GNU General Public License v2.0 only.

      The  FreeType 2  font  engine is  copyrighted  work and  cannot be  used
      legally  without a  software license.   In  order to  make this  project
      usable  to a vast  majority of  developers, we  distribute it  under two
      mutually exclusive open-source licenses.

      This means  that *you* must choose  *one* of the  two licenses described
      below, then obey  all its terms and conditions when  using FreeType 2 in
      any of your projects or products.

        - The FreeType License, found in  the file `FTL.TXT', which is similar
          to the original BSD license *with* an advertising clause that forces
          you  to  explicitly cite  the  FreeType  project  in your  product's
          documentation.  All  details are in the license  file.  This license
          is  suited  to products  which  don't  use  the GNU  General  Public
          License.

          Note that  this license  is  compatible  to the  GNU General  Public
          License version 3, but not version 2.

        - The GNU General Public License version 2, found in  `GPLv2.TXT' (any
          later version can be used  also), for programs which already use the
          GPL.  Note  that the  FTL is  incompatible  with  GPLv2 due  to  its
          advertisement clause.

      The contributed BDF and PCF drivers come with a license similar  to that
      of the X Window System.  It is compatible to the above two licenses (see
      file src/bdf/README and src/pcf/README).

      The gzip module uses the zlib license (see src/gzip/zlib.h) which too is
      compatible to the above two licenses.

      The MD5 checksum support (only used for debugging in development builds)
      is in the public domain.

                                  2006-Jan-27

                          Copyright 1996-2002, 2006 by
                David Turner, Robert Wilhelm, and Werner Lemberg

      Introduction
      ============

        The FreeType  Project is distributed in  several archive packages;
        some of them may contain, in addition to the FreeType font engine,
        various tools and  contributions which rely on, or  relate to, the
        FreeType Project.

        This  license applies  to all  files found  in such  packages, and
        which do not  fall under their own explicit  license.  The license
        affects  thus  the  FreeType   font  engine,  the  test  programs,
        documentation and makefiles, at the very least.

        This  license   was  inspired  by  the  BSD,   Artistic,  and  IJG
        (Independent JPEG  Group) licenses, which  all encourage inclusion
        and  use of  free  software in  commercial  and freeware  products
        alike.  As a consequence, its main points are that:

          o We don't promise that this software works. However, we will be
            interested in any kind of bug reports. (`as is' distribution)

          o You can  use this software for whatever you  want, in parts or
            full form, without having to pay us. (`royalty-free' usage)

          o You may not pretend that  you wrote this software.  If you use
            it, or  only parts of it,  in a program,  you must acknowledge
            somewhere  in  your  documentation  that  you  have  used  the
            FreeType code. (`credits')

        We  specifically  permit  and  encourage  the  inclusion  of  this
        software, with  or without modifications,  in commercial products.
        We  disclaim  all warranties  covering  The  FreeType Project  and
        assume no liability related to The FreeType Project.

        Finally,  many  people  asked  us  for  a  preferred  form  for  a
        credit/disclaimer to use in compliance with this license.  We thus
        encourage you to use the following text:

         """
          Portions of this software are copyright © <year> The FreeType
          Project (www.freetype.org).  All rights reserved.
         """

        Please replace <year> with the value from the FreeType version you
        actually use.

      Legal Terms
      ===========

      0. Definitions
      --------------

        Throughout this license,  the terms `package', `FreeType Project',
        and  `FreeType  archive' refer  to  the  set  of files  originally
        distributed  by the  authors  (David Turner,  Robert Wilhelm,  and
        Werner Lemberg) as the `FreeType Project', be they named as alpha,
        beta or final release.

        `You' refers to  the licensee, or person using  the project, where
        `using' is a generic term including compiling the project's source
        code as  well as linking it  to form a  `program' or `executable'.
        This  program is  referred to  as  `a program  using the  FreeType
        engine'.

        This  license applies  to all  files distributed  in  the original
        FreeType  Project,   including  all  source   code,  binaries  and
        documentation,  unless  otherwise  stated   in  the  file  in  its
        original, unmodified form as  distributed in the original archive.
        If you are  unsure whether or not a particular  file is covered by
        this license, you must contact us to verify this.

        The FreeType  Project is copyright (C) 1996-2000  by David Turner,
        Robert Wilhelm, and Werner Lemberg.  All rights reserved except as
        specified below.

      1. No Warranty
      --------------

        THE FREETYPE PROJECT  IS PROVIDED `AS IS' WITHOUT  WARRANTY OF ANY
        KIND, EITHER  EXPRESS OR IMPLIED,  INCLUDING, BUT NOT  LIMITED TO,
        WARRANTIES  OF  MERCHANTABILITY   AND  FITNESS  FOR  A  PARTICULAR
        PURPOSE.  IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
        BE LIABLE  FOR ANY DAMAGES CAUSED  BY THE USE OR  THE INABILITY TO
        USE, OF THE FREETYPE PROJECT.

      2. Redistribution
      -----------------

        This  license  grants  a  worldwide, royalty-free,  perpetual  and
        irrevocable right  and license to use,  execute, perform, compile,
        display,  copy,   create  derivative  works   of,  distribute  and
        sublicense the  FreeType Project (in  both source and  object code
        forms)  and  derivative works  thereof  for  any  purpose; and  to
        authorize others  to exercise  some or all  of the  rights granted
        herein, subject to the following conditions:

          o Redistribution of  source code  must retain this  license file
            (`FTL.TXT') unaltered; any  additions, deletions or changes to
            the original  files must be clearly  indicated in accompanying
            documentation.   The  copyright   notices  of  the  unaltered,
            original  files must  be  preserved in  all  copies of  source
            files.

          o Redistribution in binary form must provide a  disclaimer  that
            states  that  the software is based in part of the work of the
            FreeType Team,  in  the  distribution  documentation.  We also
            encourage you to put an URL to the FreeType web page  in  your
            documentation, though this isn't mandatory.

        These conditions  apply to any  software derived from or  based on
        the FreeType Project,  not just the unmodified files.   If you use
        our work, you  must acknowledge us.  However, no  fee need be paid
        to us.

      3. Advertising
      --------------

        Neither the  FreeType authors and  contributors nor you  shall use
        the name of the  other for commercial, advertising, or promotional
        purposes without specific prior written permission.

        We suggest,  but do not require, that  you use one or  more of the
        following phrases to refer  to this software in your documentation
        or advertising  materials: `FreeType Project',  `FreeType Engine',
        `FreeType library', or `FreeType Distribution'.

        As  you have  not signed  this license,  you are  not  required to
        accept  it.   However,  as  the FreeType  Project  is  copyrighted
        material, only  this license, or  another one contracted  with the
        authors, grants you  the right to use, distribute,  and modify it.
        Therefore,  by  using,  distributing,  or modifying  the  FreeType
        Project, you indicate that you understand and accept all the terms
        of this license.

      4. Contacts
      -----------

        There are two mailing lists related to FreeType:

                          GNU GENERAL PUBLIC LICENSE
                             Version 2, June 1991

       Copyright (C) 1989, 1991 Free Software Foundation, Inc.
           51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
       Everyone is permitted to copy and distribute verbatim copies
       of this license document, but changing it is not allowed.

                                  Preamble

        The licenses for most software are designed to take away your
      freedom to share and change it.  By contrast, the GNU General Public
      License is intended to guarantee your freedom to share and change free
      software--to make sure the software is free for all its users.  This
      General Public License applies to most of the Free Software
      Foundation's software and to any other program whose authors commit to
      using it.  (Some other Free Software Foundation software is covered by
      the GNU Library General Public License instead.)  You can apply it to
      your programs, too.

        When we speak of free software, we are referring to freedom, not
      price.  Our General Public Licenses are designed to make sure that you
      have the freedom to distribute copies of free software (and charge for
      this service if you wish), that you receive source code or can get it
      if you want it, that you can change the software or use pieces of it
      in new free programs; and that you know you can do these things.

        To protect your rights, we need to make restrictions that forbid
      anyone to deny you these rights or to ask you to surrender the rights.
      These restrictions translate to certain responsibilities for you if you
      distribute copies of the software, or if you modify it.

        For example, if you distribute copies of such a program, whether
      gratis or for a fee, you must give the recipients all the rights that
      you have.  You must make sure that they, too, receive or can get the
      source code.  And you must show them these terms so they know their
      rights.

        We protect your rights with two steps: (1) copyright the software, and
      (2) offer you this license which gives you legal permission to copy,
      distribute and/or modify the software.

        Also, for each author's protection and ours, we want to make certain
      that everyone understands that there is no warranty for this free
      software.  If the software is modified by someone else and passed on, we
      want its recipients to know that what they have is not the original, so
      that any problems introduced by others will not reflect on the original
      authors' reputations.

        Finally, any free program is threatened constantly by software
      patents.  We wish to avoid the danger that redistributors of a free
      program will individually obtain patent licenses, in effect making the
      program proprietary.  To prevent this, we have made it clear that any
      patent must be licensed for everyone's free use or not licensed at all.

        The precise terms and conditions for copying, distribution and
      modification follow.

                          GNU GENERAL PUBLIC LICENSE
         TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

        0. This License applies to any program or other work which contains
      a notice placed by the copyright holder saying it may be distributed
      under the terms of this General Public License.  The "Program", below,
      refers to any such program or work, and a "work based on the Program"
      means either the Program or any derivative work under copyright law:
      that is to say, a work containing the Program or a portion of it,
      either verbatim or with modifications and/or translated into another
      language.  (Hereinafter, translation is included without limitation in
      the term "modification".)  Each licensee is addressed as "you".

      Activities other than copying, distribution and modification are not
      covered by this License; they are outside its scope.  The act of
      running the Program is not restricted, and the output from the Program
      is covered only if its contents constitute a work based on the
      Program (independent of having been made by running the Program).
      Whether that is true depends on what the Program does.

        1. You may copy and distribute verbatim copies of the Program's
      source code as you receive it, in any medium, provided that you
      conspicuously and appropriately publish on each copy an appropriate
      copyright notice and disclaimer of warranty; keep intact all the
      notices that refer to this License and to the absence of any warranty;
      and give any other recipients of the Program a copy of this License
      along with the Program.

      You may charge a fee for the physical act of transferring a copy, and
      you may at your option offer warranty protection in exchange for a fee.

        2. You may modify your copy or copies of the Program or any portion
      of it, thus forming a work based on the Program, and copy and
      distribute such modifications or work under the terms of Section 1
      above, provided that you also meet all of these conditions:

          a) You must cause the modified files to carry prominent notices
          stating that you changed the files and the date of any change.

          b) You must cause any work that you distribute or publish, that in
          whole or in part contains or is derived from the Program or any
          part thereof, to be licensed as a whole at no charge to all third
          parties under the terms of this License.

          c) If the modified program normally reads commands interactively
          when run, you must cause it, when started running for such
          interactive use in the most ordinary way, to print or display an
          announcement including an appropriate copyright notice and a
          notice that there is no warranty (or else, saying that you provide
          a warranty) and that users may redistribute the program under
          these conditions, and telling the user how to view a copy of this
          License.  (Exception: if the Program itself is interactive but
          does not normally print such an announcement, your work based on
          the Program is not required to print an announcement.)

      These requirements apply to the modified work as a whole.  If
      identifiable sections of that work are not derived from the Program,
      and can be reasonably considered independent and separate works in
      themselves, then this License, and its terms, do not apply to those
      sections when you distribute them as separate works.  But when you
      distribute the same sections as part of a whole which is a work based
      on the Program, the distribution of the whole must be on the terms of
      this License, whose permissions for other licensees extend to the
      entire whole, and thus to each and every part regardless of who wrote it.

      Thus, it is not the intent of this section to claim rights or contest
      your rights to work written entirely by you; rather, the intent is to
      exercise the right to control the distribution of derivative or
      collective works based on the Program.

      In addition, mere aggregation of another work not based on the Program
      with the Program (or with a work based on the Program) on a volume of
      a storage or distribution medium does not bring the other work under
      the scope of this License.

        3. You may copy and distribute the Program (or a work based on it,
      under Section 2) in object code or executable form under the terms of
      Sections 1 and 2 above provided that you also do one of the following:

          a) Accompany it with the complete corresponding machine-readable
          source code, which must be distributed under the terms of Sections
          1 and 2 above on a medium customarily used for software interchange; or,

          b) Accompany it with a written offer, valid for at least three
          years, to give any third party, for a charge no more than your
          cost of physically performing source distribution, a complete
          machine-readable copy of the corresponding source code, to be
          distributed under the terms of Sections 1 and 2 above on a medium
          customarily used for software interchange; or,

          c) Accompany it with the information you received as to the offer
          to distribute corresponding source code.  (This alternative is
          allowed only for noncommercial distribution and only if you
          received the program in object code or executable form with such
          an offer, in accord with Subsection b above.)

      The source code for a work means the preferred form of the work for
      making modifications to it.  For an executable work, complete source
      code means all the source code for all modules it contains, plus any
      associated interface definition files, plus the scripts used to
      control compilation and installation of the executable.  However, as a
      special exception, the source code distributed need not include
      anything that is normally distributed (in either source or binary
      form) with the major components (compiler, kernel, and so on) of the
      operating system on which the executable runs, unless that component
      itself accompanies the executable.

      If distribution of executable or object code is made by offering
      access to copy from a designated place, then offering equivalent
      access to copy the source code from the same place counts as
      distribution of the source code, even though third parties are not
      compelled to copy the source along with the object code.

        4. You may not copy, modify, sublicense, or distribute the Program
      except as expressly provided under this License.  Any attempt
      otherwise to copy, modify, sublicense or distribute the Program is
      void, and will automatically terminate your rights under this License.
      However, parties who have received copies, or rights, from you under
      this License will not have their licenses terminated so long as such
      parties remain in full compliance.

        5. You are not required to accept this License, since you have not
      signed it.  However, nothing else grants you permission to modify or
      distribute the Program or its derivative works.  These actions are
      prohibited by law if you do not accept this License.  Therefore, by
      modifying or distributing the Program (or any work based on the
      Program), you indicate your acceptance of this License to do so, and
      all its terms and conditions for copying, distributing or modifying
      the Program or works based on it.

        6. Each time you redistribute the Program (or any work based on the
      Program), the recipient automatically receives a license from the
      original licensor to copy, distribute or modify the Program subject to
      these terms and conditions.  You may not impose any further
      restrictions on the recipients' exercise of the rights granted herein.
      You are not responsible for enforcing compliance by third parties to
      this License.

        7. If, as a consequence of a court judgment or allegation of patent
      infringement or for any other reason (not limited to patent issues),
      conditions are imposed on you (whether by court order, agreement or
      otherwise) that contradict the conditions of this License, they do not
      excuse you from the conditions of this License.  If you cannot
      distribute so as to satisfy simultaneously your obligations under this
      License and any other pertinent obligations, then as a consequence you
      may not distribute the Program at all.  For example, if a patent
      license would not permit royalty-free redistribution of the Program by
      all those who receive copies directly or indirectly through you, then
      the only way you could satisfy both it and this License would be to
      refrain entirely from distribution of the Program.

      If any portion of this section is held invalid or unenforceable under
      any particular circumstance, the balance of the section is intended to
      apply and the section as a whole is intended to apply in other
      circumstances.

      It is not the purpose of this section to induce you to infringe any
      patents or other property right claims or to contest validity of any
      such claims; this section has the sole purpose of protecting the
      integrity of the free software distribution system, which is
      implemented by public license practices.  Many people have made
      generous contributions to the wide range of software distributed
      through that system in reliance on consistent application of that
      system; it is up to the author/donor to decide if he or she is willing
      to distribute software through any other system and a licensee cannot
      impose that choice.

      This section is intended to make thoroughly clear what is believed to
      be a consequence of the rest of this License.

        8. If the distribution and/or use of the Program is restricted in
      certain countries either by patents or by copyrighted interfaces, the
      original copyright holder who places the Program under this License
      may add an explicit geographical distribution limitation excluding
      those countries, so that distribution is permitted only in or among
      countries not thus excluded.  In such case, this License incorporates
      the limitation as if written in the body of this License.

        9. The Free Software Foundation may publish revised and/or new versions
      of the General Public License from time to time.  Such new versions will
      be similar in spirit to the present version, but may differ in detail to
      address new problems or concerns.

      Each version is given a distinguishing version number.  If the Program
      specifies a version number of this License which applies to it and "any
      later version", you have the option of following the terms and conditions
      either of that version or of any later version published by the Free
      Software Foundation.  If the Program does not specify a version number of
      this License, you may choose any version ever published by the Free Software
      Foundation.

        10. If you wish to incorporate parts of the Program into other free
      programs whose distribution conditions are different, write to the author
      to ask for permission.  For software which is copyrighted by the Free
      Software Foundation, write to the Free Software Foundation; we sometimes
      make exceptions for this.  Our decision will be guided by the two goals
      of preserving the free status of all derivatives of our free software and

                                  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.

                  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 St, 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 Library General
      Public License instead of this License.
