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.
|
|
|
|
