I'm affraid my question isn't strictly to do with programming perl.
At the moment i'm just finishing off my dissertation for my degree. It's gone really well, i've developed a web spider in Perl using libwww perl modules, that gets information about the various technologies being used on the web to create web pages.
Actually if anyone is interested in my final results, you can see them at http://www.webchalkboard.com/bot/
Anyway, my problem at the moment is deciding the best way describe how my program work. I've tried drawing a JSD structure diagram, but that doesn't really show how all my sub routines work together. If I was describing an object orientated system I could draw a class diagram. But what's the best way to represent how a Perl program works? I want to demonstrate how the main program calls the various sub routines which perform tasks, and then return to the main program again.
I hope that's all clear, thanks,
