About
--------------
A Freetype wrapper for use with allegro
Feel free to do whatever you like with this, by all means enjoy!
Just add it to your project
--------------
Linking
--------------
on linux:
g++ `freetype-config --cflags` ftalleg.cpp myfiles.cpp `freetype-config --libs` `allegro-config --libs`
on windows (you may need to include the freetype dir location, ie -Ic:/mingw/include):
g++ ftalleg.cpp myfiles.cpp -lfreetype -lalleg
