This is an ongoing project with the aim of providing a help file for LaTeX (and its friends like ConTeXt, Metapost, Metafont, etc.) using a state-of-the-art source format, aka DocBook/XML.
Any additions to this Reference should only be made to the DocBook source file.
Various output formats can already be generated out of this source file. More formats to come. Anybody is encouraged to write a converter for his own desired output format. Because the source file is XML, the easiest way might be to use XSLT.
Anybody interested in contributing to this project should contact the authors.
