MoinMoin/Filter

For converting MoinMoin wikitext to MediaWiki wikitext, Dan Littlejohn's mm2mw.pl Perl script is the least-worst option.

Below is a version of Filter that includes a few more syntax conversions and also converts simple tables. Feel free to enhance.

The original version of the code on this page is by Dan Littlejohn with patches by Tyler Drake. A license was not given in the original file (though it was made available at no cost to all); David Gerard is contacting Mr Littlejohn to ask. It's not GFDL.
