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).
