+Source: ftgl
+Version: 2.3.1
+Description: FTGL is a free open source library to enable developers to use arbitrary fonts in their OpenGL (www.opengl.org) applications.
+  Unlike other OpenGL font libraries FTGL uses standard font file formats so doesn't need a preprocessing step to convert the high quality font data into a lesser quality, proprietary format.
+  FTGL uses the Freetype (www.freetype.org) font library to open and 'decode' the fonts. It then takes that output and stores it in a format most efficient for OpenGL rendering.
+Build-Depends: freetype, opengl
