I think you might misunderstand what the software does. It's a general Perl module for
doing the conversion. The web page I mentioned is merely somebody's user interface
slapped on top of the module. It should be easy for any Perl programmer to write a script
that processes your 300 HTML files using the module, and produces 300 Wikitext files,
which you can then import into the wiki with a standard MediaWiki maintenance script. An
intermediate-level Perl programmer should be able to do this in a few hours max.
That looks like it would work for a page or two. I'm looking for a way to
atomate the process. The main issue we are experiancing isn't altering the
syntax to wiki markup but actually importing it into the db. We are trying
to streamline the process so it doens't require days of pasting content.
