It's truly general-purpose and thoroughly tested at the moment though it's currently a subproject of my logic circuit simulator, Tesla , which uses it as the core.
There is some (English) POD in the .pm files of Sim and I've also written a trivial M/M/1 and M/M/m sample app here:
A corresponding report with some code snippets and interesting pictures can also be found here:
Sorry for the Chinese characters in this report, but there is always a Google Translate :)
If you find this thing useful, I may feel like putting it onto CPAN.
Hope this helps.
