MediaWiki support

[Johannes Schindelin]

Hi,

I just hacked mediawiki a bit in order to embed music in wikipedia. I use
lilypond-book for this (I know, I know, it is overkill. But it's easy,
too!). To use my work, apply the patch and in LocalSettings.php, set
$wgUseLilypond = true and $wgLilypondBook according to your installation.

The only reason I am posting this here, and not on the mediawiki list, is
that I don't really know if there are security issues. I thought I could
specify

        lilypond-book -P "lilypond --safe" --output out test.html

in order to be on the safe side, but lilypond fails (output below). Note
that a similar error occurs when just specifying -P lilypond. Is this the
way to go, or is it my mistake?

Ciao,
Dscho
