Extension:MscGen

MscGen extension allows to display Message Sequence Chart's. It allows to display message flows. Flowchart was my first attempt to include such in MediaWiki, but recently I found the neat tool from http://www.mcternan.me.uk/mscgen/index.html which had been inspired by graphViz.

The code needs some cleaning up, but works. 

Code
This is the previous code with the GraphViz references removed so that it can coexist more peacefully with GraphViz. This code was installed in extensions/MSC.php and then included in LocalSettings.php.

Conversion from Flowchart to Mscgen
You can use the following perl script to convert from flowchart to mscgen

Extension to for other graphviz tools
