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.

Neither the FreeType authors and contributors nor
