Some programs I've written.
rst2chm generates Microsoft (TM) HTML Help files from one or more reStructuredText source files. It is written in Python requires both Docutils and the Microsoft (TM) HTML Help Workshop.
rst2ht is a writer for Docutils which converts reStructuredText to an .ht template, for use with ht2html.
xChecker is a utility I wrote a couple years ago for validating XML documents. I wrote it using Delphi and and MSXML (Microsoft's XML parser).
