For documentation writing we use LYX (http://www.lyx.org). The LYX files are the source for both TEX and HTML. If you wish to contribute toward the documentation, please do not edit changes directly in the .lyx file but send your changes to me for merging. It is much easier if you create a separate .lyx file for your documentation, and for one of the maintainers can then merge it into the documentation.
On a daily basis i will generate TEX and HTML files. The new HTML documents will be available on the web site shortly after. For program code examples please use the ``LYX-code'' style.
