Freetype Project License or GNU General Public License v2.0 only.
The FreeType 2 font engine is copyrighted work and cannot be used
legally without a software license. In order to make this project
usable to a vast majority of developers, we distribute it under two
mutually exclusive open-source licenses.
This means that *you* must choose *one* of the two licenses described
below, then obey all its terms and conditions when using FreeType 2 in
any of your projects or products.
- The FreeType License, found in the file `FTL.TXT', which is similar
to the original BSD license *with* an advertising clause that forces
you to explicitly cite the FreeType project in your product's
documentation. All details are in the license file. This license
is suited to products which don't use the GNU General Public
License.
Note that this license is compatible to the GNU General Public
License version 3, but not version 2.
- The GNU General Public License version 2, found in `GPLv2.TXT' (any
later version can be used also), for programs which already use the
GPL. Note that the FTL is incompatible with GPLv2 due to its
advertisement clause.
The contributed BDF and PCF drivers come with a license similar to that
of the X Window System. It is compatible to the above two licenses (see
file src/bdf/README and src/pcf/README). The same holds for the files
`fthash.c' and `fthash.h'; their code was part of the BDF driver in
earlier FreeType versions.
The gzip module uses the zlib license (see src/gzip/zlib.h) which too is
compatible to the above two licenses.
The MD5 checksum support (only used for debugging in development builds)
is in the public domain.
