ttLib: Read and write OpenType and TrueType fonts

Most users of the fontTools library will be using it to generate or manipulate OpenType and TrueType fonts. (FontTools initially only supported TrueType fonts, gaining OpenType support in version 2.0, and so uses the tt prefix to refer to both kinds of font. Because of this we will refer to both as “TrueType fonts” unless we need to make a distinction.)

The main entry point for such operations is the fontTools.ttLib.ttFont module, but other modules also provide useful functionality for handling OpenType fonts.
