this module could be used in a wiki-like system, but is intended to be more generic. It could also be used in a shlashdot or perlmonks type system, or for allowing non-HTML -speaking folks to post "what's new" notes on a website (so that you don't have to do it for them every week).
The module is supposed to be a plug-in to whatever larger-scope project you might have that needs to take some user input and turn it into html.
Should I read your comment as "you're re-inventing the wheel" (and if so, which perl modules should I be looking at) or as "could you support wiki input sytax as well"?
