A MoinMoin 1.2.x -> MediaWiki 1.7.x converter
To use this, just find the base name of your MoinMoin Wiki and the base name of your new MediaWiki installations, and feed them to mm2mw-wiki. Tested only on Emacs 22, requires at least a url library with the ability to do HTTP POSTs. Check the *Messages* buffer to see how it did, per page. My MoinMoin wiki was v1.2.x, so I have absolutely no idea if it will work on later versions. This might give somebody a good start, though. I don't claim that it supports everything; it definitely does not handle attachments correctly. There are probably better ways to do everything but I built this in a couple of days from scratch for my own purposes, and if God is good to me I will not have to do it again. I ripped the wikiname regexp from oddmuse.el and the url HTTP POST code from an example on EmacsWiki; beyond that I wrote this on my own.
