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

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 fi les 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 makefi les, 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 specifi cally permit and encourage the inclusion of this software, with or without modifi cations, 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. Defi nitions
-------------------
Throughout this license, the terms `package’, `FreeType Project’, and `FreeType archive’ refer to the set of fi les originally distributed by the authors
(David Turner, Robert Wilhelm, and Werner Lemberg) as the `FreeType Project’, be they named as alpha, beta or fi nal 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 fi les distributed in the original FreeType Project, including all source code, binaries and documentation, unless otherwise
stated in the fi le in its original, unmodifi ed form as distributed in the original archive. If you are unsure whether or not a particular fi le 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 specifi ed
below.

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

2. Redistribution
-----------------------
This license grants a worldwide, royalty-free, perpetual and irrevocable right and license to use, execute, perform, compile, display, copy, create

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 fi le (`FTL.TXT’) unaltered; any additions, deletions or changes to the original fi les must be
clearly indicated in accompanying documentation. The copyright notices of the unaltered, original fi les must be preserved in all copies of source
fi les.
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 unmodifi ed fi les. 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
specifi c 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.
