Open CASCADE Technology is used under the GNU Lesser General Public License (LGPL) version 2.1 with additional exception.

Text of the license and exception follows.

    		  GNU LESSER GENERAL PUBLIC LICENSE
    		       Version 2.1, February 1999

     Copyright (C) 1991, 1999 Free Software Foundation, Inc.
     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
     Everyone is permitted to copy and distribute verbatim copies
     of this license document, but changing it is not allowed.

    [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., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  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
      Ty Coon, President of Vice

    That's all there is to it!

OPEN CASCADE EXCEPTION (VERSION 1.0) TO GNU LGPL VERSION 2.1.

    p>The object code (i.e. not a source) form of a "work that uses the Library"
    can incorporate material from a header file that is part of the Library.

    As a special exception to the GNU Lesser General Public License version 2.1,
    you may distribute such object code incorporating material from header files
    provided with the Open CASCADE Technology libraries
    (including code of CDL generic classes) under terms of your choice,
    provided that you give prominent notice in supporting documentation to this code
    that it makes use of or is based on facilities provided by the Open CASCADE Technology software.

                        ----------------------------

                                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 ©  The FreeType
        Project (www.freetype.org).  All rights reserved.
       """

      Please replace  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.

      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.

    (b) under patents now or hereafter owned or controlled by Initial Developer, to make, have made, use and sell ("Utilize") the Original Code (or portions thereof), but solely to the extent that
    any such patent is reasonably necessary to enable You to Utilize the Original Code (or portions thereof) and not to any greater extent that may be necessary to Utilize further Modifications or
    combinations.

    2.2. Contributor Grant.
    Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license, subject to third party intellectual property claims:

    (a) to use, reproduce, modify, display, perform, sublicense and distribute the Modifications created by such Contributor (or portions thereof) either on an unmodified basis, with other Modifications, as Covered Code or as part of a Larger Work; and

    (b) under patents now or hereafter owned or controlled by Contributor, to Utilize the Contributor Version (or portions thereof), but solely to the extent that any such patent is reasonably necessary to enable You to Utilize the Contributor Version (or portions thereof), and not to any greater extent that
    may be necessary to Utilize further Modifications or combinations.

    3. Distribution Obligations.

    3.1. Application of License.
    The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2. The Source Code version of Covered Code may be distributed only under the terms of this License or a future version of this License released under Section 6.1, and You must include a copy of this License with every copy of the Source Code You distribute. You may not offer or impose any terms on any Source Code version that alters or
    restricts the applicable version of this License or the recipients' rights hereunder. However, You may include an additional document offering the additional rights described in Section 3.5.

    3.2. Availability of Source Code.
    Any Modification which You create or to which You contribute must be made available in Source Code form under the terms of this License either on the same media as an Executable version or via an accepted Electronic Distribution Mechanism to anyone to whom you made an Executable version available; and if made available via Electronic Distribution Mechanism, must remain available for at least twelve (12) months after the date it initially became available, or at least six (6) months after a subsequent version of that particular Modification has been made available to such recipients. You are responsible for ensuring that the Source Code version remains available even if the Electronic Distribution Mechanism is maintained by a third party.

    3.3. Description of Modifications.
    You must cause all Covered Code to which you contribute to contain a file documenting the changes You made to create that Covered Code and the date of any change. You must include a prominent statement that the Modification is derived, directly or indirectly, from Original Code provided by the Initial Developer and including the name of the Initial Developer in (a) the Source Code, and (b) in any notice in an Executable version or related documentation in which You describe the origin or ownership of the Covered Code.

    3.4. Intellectual Property Matters

    (a) Third Party Claims.
    If You have knowledge that a party claims an intellectual property right in particular functionality or code (or its utilization under this License), you must include a text file with the source code distribution titled "LEGAL" which describes the claim and the party making the claim in sufficient detail that a recipient will know whom to contact. If you obtain such knowledge after You make Your Modification available as described in Section 3.2, You shall promptly modify the LEGAL file in all copies You make
    available thereafter and shall take other steps (such as notifying appropriate mailing lists or newsgroups) reasonably calculated to inform those who received the Covered Code that new knowledge has been obtained.

    (b) Contributor APIs.
    If Your Modification is an application programming interface and You own or control patents which are reasonably necessary to implement that API, you must also include this information in the LEGAL file.

    3.5. Required Notices.
    You must duplicate the notice in Exhibit A in each file of the Source Code, and this License in any documentation for the Source Code, where You describe recipients' rights relating to Covered Code. If You created one or more Modification(s), You may add your name as a Contributor to the notice described in Exhibit A. If it is not possible to put such notice in a particular Source Code file due to its
    structure, then you must include such notice in a location (such as a relevant directory file) where a user would be likely to look for such a notice. You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Code. However, You may do so only on Your own behalf, and not on behalf of the Initial Developer or any Contributor. You must make it absolutely clear than any such warranty, support, indemnity or
    liability obligation is offered by You alone, and You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of
    warranty, support, indemnity or liability terms You offer.

    3.6. Distribution of Executable Versions.
    You may distribute Covered Code in Executable form only if the requirements of Section 3.1-3.5 have been met for that Covered Code, and if You include a notice stating that the Source Code version of the Covered Code is available under the terms of this License, including a description of how and where You have fulfilled the obligations of Section 3.2. The notice must be conspicuously included in any notice in an Executable version, related documentation or collateral in which You
    describe recipients' rights relating to the Covered Code. You may distribute the Executable version of Covered Code under a license of Your choice, which may contain terms different from this License,
    provided that You are in compliance with the terms of this License and that the license for the Executable version does not attempt to limit or alter the recipient's rights in the Source Code version from the rights set forth in this License. If You distribute the Executable version under a different license You must make it absolutely clear that any terms which differ from this License are offered by You alone, not by the Initial Developer or any Contributor. You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of any such terms You offer.

    3.7. Larger Works.
    You may create a Larger Work by combining Covered Code with other code not governed by the terms of this License and distribute the Larger Work as a single product. In such a case, You must make sure the requirements of this License are fulfilled for the Covered Code.

    4. Inability to Comply Due to Statute or Regulation.

    If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Code due to statute or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be included in the LEGAL file described in Section 3.4 and must be included with all distributions of the Source Code. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it.

    5. Application of this License.

    This License applies to code to which the Initial Developer has attached the notice in Exhibit A, and to related Covered Code.

    6. Versions of the License.

    6.1. New Versions.
    Floris van den Berg may publish revised and/or new versions of the License from time to time. Each version will be given a distinguishing version number.

    6.2. Effect of New Versions.
    Once Covered Code has been published under a particular version of the License, You may always continue to use it under the terms of that version. You may also choose to use such Covered Code under the terms of any subsequent version of the License published by Floris van den Berg
    No one other than Floris van den Berg has the right to modify the terms applicable to Covered Code created under this License.

    6.3. Derivative Works.
    If you create or use a modified version of this License (which you may only do in order to apply it to code which is not already Covered Code governed by this License), you must (a) rename Your license so that the phrases "FreeImage", `FreeImage Public License", "FIPL", or any confusingly similar phrase do not appear anywhere in your license and (b) otherwise make it clear that your version of the license contains terms which differ from the FreeImage Public License. (Filling in the name of the Initial Developer, Original Code or Contributor in the notice described in Exhibit A shall not of themselves be deemed to be modifications of this License.)

    7. DISCLAIMER OF WARRANTY.

    COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

    8. TERMINATION.

    This License and the rights granted hereunder will terminate automatically if You fail to comply with terms herein and fail to cure such breach within 30 days of becoming aware of the breach. All sublicenses to the Covered Code which are properly granted shall survive any termination of this License. Provisions which, by their nature, must remain in effect beyond the termination of this License shall survive.

    9. LIMITATION OF LIABILITY.

    UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO YOU OR ANY OTHER PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
    EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THAT EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.

    10. U.S. GOVERNMENT END USERS.

    The Covered Code is a "commercial item," as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" and "commercial computer software documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Covered Code with only those rights set forth herein.

    11. MISCELLANEOUS.

    This License represents the complete agreement concerning subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. This License shall be governed by Dutch law provisions (except to the extent applicable law, if any, provides otherwise), excluding its conflict-of-law provisions. With respect to disputes in which at least one party is a citizen of, or an entity chartered or registered to do business in, the The Netherlands: (a) unless otherwise agreed in writing, all disputes relating to this License (excepting any dispute relating to intellectual property rights) shall be subject to final and binding arbitration, with the losing party paying all costs of arbitration; (b) any arbitration relating to this Agreement shall be held in Almelo, The Netherlands; and (c) any litigation relating to this Agreement shall be subject to the jurisdiction of the court of Almelo, The Netherlands with the losing party responsible for costs, including without limitation, court costs and reasonable attorneys fees and expenses. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not apply to this License.

    12. RESPONSIBILITY FOR CLAIMS.

    Except in cases where another Contributor has failed to comply with Section 3.4, You are responsible for damages arising, directly or indirectly, out of Your utilization of rights under this License, based
    on the number of copies of Covered Code you made available, the revenues you received from utilizing such rights, and other relevant factors. You agree to work with affected parties to distribute
    responsibility on an equitable basis.

The text of the license follows.

    Creative Commons Legal Code

    CC0 1.0 Universal

        CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
        LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
        ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
        INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
        REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
        PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
        THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
        HEREUNDER.

    Statement of Purpose

    The laws of most jurisdictions throughout the world automatically confer
    exclusive Copyright and Related Rights (defined below) upon the creator
    and subsequent owner(s) (each and all, an "owner") of an original work of
    authorship and/or a database (each, a "Work").

    Certain owners wish to permanently relinquish those rights to a Work for
    the purpose of contributing to a commons of creative, cultural and
    scientific works ("Commons") that the public can reliably and without fear
    of later claims of infringement build upon, modify, incorporate in other
    works, reuse and redistribute as freely as possible in any form whatsoever
    and for any purposes, including without limitation commercial purposes.
    These owners may contribute to the Commons to promote the ideal of a free
    culture and the further production of creative, cultural and scientific
    works, or to gain reputation or greater distribution for their Work in
    part through the use and efforts of others.

    For these and/or other purposes and motivations, and without any
    expectation of additional consideration or compensation, the person
    associating CC0 with a Work (the "Affirmer"), to the extent that he or she
    is an owner of Copyright and Related Rights in the Work, voluntarily
    elects to apply CC0 to the Work and publicly distribute the Work under its
    terms, with knowledge of his or her Copyright and Related Rights in the
    Work and the meaning and intended legal effect of CC0 on those rights.

    1. Copyright and Related Rights. A Work made available under CC0 may be
    protected by copyright and related or neighboring rights ("Copyright and
    Related Rights"). Copyright and Related Rights include, but are not
    limited to, the following:

      i. the right to reproduce, adapt, distribute, perform, display,
         communicate, and translate a Work;
     ii. moral rights retained by the original author(s) and/or performer(s);
    iii. publicity and privacy rights pertaining to a person's image or
         likeness depicted in a Work;
     iv. rights protecting against unfair competition in regards to a Work,
         subject to the limitations in paragraph 4(a), below;
      v. rights protecting the extraction, dissemination, use and reuse of data
         in a Work;
     vi. database rights (such as those arising under Directive 96/9/EC of the
         European Parliament and of the Council of 11 March 1996 on the legal
         protection of databases, and under any national implementation
         thereof, including any amended or successor version of such
         directive); and
    vii. other similar, equivalent or corresponding rights throughout the
         world based on applicable law or treaty, and any national
         implementations thereof.

    2. Waiver. To the greatest extent permitted by, but not in contravention
    of, applicable law, Affirmer hereby overtly, fully, permanently,
    irrevocably and unconditionally waives, abandons, and surrenders all of
    Affirmer's Copyright and Related Rights and associated claims and causes
    of action, whether now known or unknown (including existing as well as
    future claims and causes of action), in the Work (i) in all territories
    worldwide, (ii) for the maximum duration provided by applicable law or
    treaty (including future time extensions), (iii) in any current or future
    medium and for any number of copies, and (iv) for any purpose whatsoever,
    including without limitation commercial, advertising or promotional
    purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
    member of the public at large and to the detriment of Affirmer's heirs and
    successors, fully intending that such Waiver shall not be subject to
    revocation, rescission, cancellation, termination, or any other legal or
    equitable action to disrupt the quiet enjoyment of the Work by the public
    as contemplated by Affirmer's express Statement of Purpose.

    3. Public License Fallback. Should any part of the Waiver for any reason
    be judged legally invalid or ineffective under applicable law, then the
    Waiver shall be preserved to the maximum extent permitted taking into
    account Affirmer's express Statement of Purpose. In addition, to the
    extent the Waiver is so judged Affirmer hereby grants to each affected
    person a royalty-free, non transferable, non sublicensable, non exclusive,
    irrevocable and unconditional license to exercise Affirmer's Copyright and
    Related Rights in the Work (i) in all territories worldwide, (ii) for the
    maximum duration provided by applicable law or treaty (including future
    time extensions), (iii) in any current or future medium and for any number
    of copies, and (iv) for any purpose whatsoever, including without
    limitation commercial, advertising or promotional purposes (the
    "License"). The License shall be deemed effective as of the date CC0 was
    applied by Affirmer to the Work. Should any part of the License for any
    reason be judged legally invalid or ineffective under applicable law, such
    partial invalidity or ineffectiveness shall not invalidate the remainder
    of the License, and in such case Affirmer hereby affirms that he or she
    will not (i) exercise any of his or her remaining Copyright and Related
    Rights in the Work or (ii) assert any associated claims and causes of
    action with respect to the Work, in either case contrary to Affirmer's
    express Statement of Purpose.

    4. Limitations and Disclaimers.

     a. No trademark or patent rights held by Affirmer are waived, abandoned,
        surrendered, licensed or otherwise affected by this document.
     b. Affirmer offers the Work as-is and makes no representations or
        warranties of any kind concerning the Work, express, implied,
        statutory or otherwise, including without limitation warranties of
        title, merchantability, fitness for a particular purpose, non
        infringement, or the absence of latent or other defects, accuracy, or
        the present or absence of errors, whether or not discoverable, all to
        the greatest extent permissible under applicable law.
     c. Affirmer disclaims responsibility for clearing rights of other persons
        that may apply to the Work or any use thereof, including without
        limitation any person's Copyright and Related Rights in the Work.
        Further, Affirmer disclaims responsibility for obtaining any necessary
        consents, permissions or other rights required for any use of the
        Work.
     d. Affirmer understands and acknowledges that Creative Commons is not a
        party to this document and has no duty or obligation with respect to
        this CC0 or use of the Work.
