I'm proud to announce a Brand New Release of FontTools/TTX, an Open Source Python library and toolkit to manipulate fonts.
This is the first beta of version 2.0 -- I intend to release 2.0 final in a couple of months.
TTX is a tool to convert TrueType and OpenType fonts to an XML-based text format (also called "TTX") and back. This enables you to edit TTF/OTF tables with a text editor. It's a low level tool, meant for people who are not scared to fiddle with technical details of the OT format. It is implemented in Python.
FontTools is a Python library implementing reading and writing of TrueType fonts, OpenType fonts, AFM files, reading of Type 1 fonts (writing is still being planned), and some other formats.
