LilyPond extension/plugin for MediaWiki software

[Mark Dewey]

Hello,

I've heard tell that there is a LilyPond extension or plugin for MediaWiki 
(that's the software they use with Wikipedia).  I have a wiki (HymnWiki.org) 
that uses LilyPond files quite a bit . . . so, I'm interested in finding out 
what the plugin is for, what it is called, and where I can get it.  Do any of 
you know?  Would it be better to ask on a MediaWiki forum?  I figured the 
person who made it probably frequents these forums from time to time, anyway.

I've heard that it requires LilyPond to be installed on the server.  Is this 
true?

I'm guessing it allows scores to show up, or plays the music, or something, but 
I really have no idea other than that.  Whatever the case, my Internet searches 
haven't yielded much.
