+<a href="http://celtx.com/">Celtx</a> - an open-source application that
+allows one to edit screenplays, novels, and other media pre-production
+resources. Uses well-formed HTML 4 for its data files, packaged in a
+.zip with many resources, so it may be less ideal than XML. It is also a GUI
+program that was quite sluggish from my experience.
+<a href="http://www.methods.co.nz/asciidoc/">AsciiDoc</a> - a very rich
+and open-source markup language that can be used for notating text and can
+be converted into DocBook 4, directly into HTML, and several other formats.
