I'd be interested to know the answer to that.  I don't _think_ it's an 
additional dependency,  but there could be a version issue.

Good point.  I didn't think about it,  because it's moot in my web 

One thing that's occurred to me since the initial implementation is that 
it might be better to push more of the conversion logic into the 
JavaScript,  using XmlHttpRequest to call PmWiki actions that convert 
the wiki markup to HTML after the page load and the HTML to wiki markup 
on submit.

I've also considered reimplementing the WikiConverter in PHP,  but that 
seems like a bit much effort to go to at this point.
