		The FreeType Project LICENSE
		----------------------------

		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 Š <year> The FreeType
		Project (www.freetype.org).  All rights reserved.
		"""

		Please replace &lt;year&gt; 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:

		o freetype@nongnu.org

		Discusses general use and applications of FreeType, as well as
		future and  wanted additions to the  library and distribution.
		If  you are looking  for support,  start in  this list  if you
		haven't found anything to help you in the documentation.

		o freetype-devel@nongnu.org

		Discusses bugs,  as well  as engine internals,  design issues,

					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
		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.

			&lt;one line to give the program's name and a brief idea of what it does.&gt;
			Copyright (C) &lt;year&gt;  &lt;name of author&gt;

			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.

		  &lt;signature of Ty Coon&gt;, 1 April 1989
		  Ty Coon, President of Vice

		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.

		The C preprocessor is now (mostly?) ANSI C compliant, and some tweaks have
		been applied to also make it fairly usable to process other data files, such
