What do you think of Pandoc? http://pandoc.org/
The two supported wiki markups:
- MediaWiki https://www.mediawiki.org/wiki/Help:Formatting
- TWiki http://twiki.org/cgi-bin/view/TWiki/TextFormattingRules
I wonder which one is the closest to WikiWikiWeb syntax.
Another cool stuff would be to put that in the gopherspace.
