FreeType 2.5.4
==============
Homepage: http://www.freetype.org
FreeType is a freely available software library to render fonts.
It is written in C, designed to be small, efficient, highly
customizable, and portable while capable of producing high-quality
output (glyph images) of most vector and bitmap font formats.
Please read the docs/CHANGES file, it contains IMPORTANT
INFORMATION.
Read the files `docs/INSTALL*' for installation instructions; see
the file `docs/LICENSE.TXT' for the available licenses.
The FreeType 2 API reference is located in `docs/reference'; use the
file `ft2-toc.html' as the top entry point. Additional
documentation is available as a separate package from our sites. Go
to
http://download.savannah.gnu.org/releases/freetype/
and download one of the following files.
freetype-doc-2.5.4.tar.bz2
freetype-doc-2.5.4.tar.gz
ftdoc254.zip
To view the documentation online, go to
http://www.freetype.org/freetype2/documentation.html
Mailing Lists
=============
The preferred way of communication with the FreeType team is using
e-mail lists.
general use and discussion: freetype@nongnu.org
engine internals, porting, etc.: freetype-devel@nongnu.org
announcements: freetype-announce@nongnu.org
The lists are moderated; see
http://www.freetype.org/contact.html
how to subscribe.
Bugs
====
Please submit bug reports at
https://savannah.nongnu.org/bugs/?group=freetype
Alternatively, you might report bugs by e-mail to
`freetype-devel@nongnu.org'. Don't forget to send a detailed
explanation of the problem -- there is nothing worse than receiving
a terse message that only says `it doesn't work'.
Enjoy!
The FreeType Team
