Eric S. Raymond has released doclifter 2.0, an open source tool that transcodes {n,t,g}roff documentation to DocBook. Version 2.0 adds support for man, mandoc, ms, me, and TkMan source documents as well. Raymond claims the "result is usable without further hand-hacking about 95% of the time." This release fixes bugs. Doclifter is written in Python, and requires Python 2.2a1. doclifter is published under the GPL.
Peter Jipsen has released ASCIIMathML 1.4.3, a JavaScript program that converts calculator-style ASCII math notation and some LaTeX formulas to Presentation MathML while a Web page loads. The resulting MathML can be displayed in Mozilla-based browsers and Internet Explorer 6 with MathPlayer.
