| 2 | ----------------- |
| 3 | |
| 4 | The FreeType 2 font engine is copyrighted work and cannot be used |
| 5 | legally without a software license. In order to make this project |
| 6 | usable to a vast majority of developers, we distribute it under two |
| 7 | mutually exclusive open-source licenses. |
| 8 | |
| 9 | This means that *you* must choose *one* of the two licenses described |
| 10 | below, then obey all its terms and conditions when using FreeType 2 in |
| 11 | any of your projects or products. |
| 12 | |
| 13 | - The FreeType License, found in the file `docs/FTL.TXT`, which is |
| 14 | similar to the original BSD license *with* an advertising clause |
| 15 | that forces you to explicitly cite the FreeType project in your |
| 16 | product's documentation. All details are in the license file. |
| 17 | This license is suited to products which don't use the GNU General |
| 18 | Public License. |
| 19 | |
| 20 | Note that this license is compatible to the GNU General Public |
| 21 | License version 3, but not version 2. |
| 22 | |
| 23 | - The GNU General Public License version 2, found in |
| 24 | `docs/GPLv2.TXT` (any later version can be used also), for |
| 25 | programs which already use the GPL. Note that the FTL is |
| 26 | incompatible with GPLv2 due to its advertisement clause. |
| 27 | |
| 28 | The contributed BDF and PCF drivers come with a license similar to |
| 29 | that of the X Window System. It is compatible to the above two |
| 30 | licenses (see files `src/bdf/README` and `src/pcf/README`). The same |
| 31 | holds for the source code files `src/base/fthash.c` and |
| 32 | `include/freetype/internal/fthash.h`; they wer part of the BDF driver |
| 33 | in earlier FreeType versions. |
| 34 | |
| 35 | The gzip module uses the zlib license (see `src/gzip/zlib.h`) which |
| 36 | too is compatible to the above two licenses. |
| 37 | |
| 38 | The MD5 checksum support (only used for debugging in development |
| 39 | builds) is in the public domain. |
