A command line app written in Java which, using the Xalan XML parser and an XSLT stylesheet, allows you to convert native AbiWord, (*.abw), files into HTML pages. Features include being able to convert a single file or batch convert a directory of files and turning http:// web address references into anchor tags under HTML. For more information see the README and CHANGELOG files.
Kinda cool, but as another idea how about a MovableType plug-in that takes a .abw file upload and translates it to embeded (X)HTML?
