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:
We don’t promise that this software works. However, we will
be interested in any kind of bug reports. (`as is’ distribution)
You can use this software for whatever you want, in parts or
full form, without having to pay us. (`royalty-free’ usage)
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.
