A few weeks ago I was looking for a way to convert my text notes to HTML and started looking at syntax used by other tools. Since then I’ve been liking Wikis more and more.
Radeox is a library that converts text to XHTML. It can be used in Wikis, and it is used in the SnipSnap Wiki. But more importantly for me, it can be used as a command line tool or as a library in Java applications. Radeox accepts this syntax by default, but is customizable to meet my needs.
