Okay, I've gone through the exercise of creating a partial installation
that only includes a few bits and pieces, where the properties file is
written by the parent application. As might be expected in this process
I keep hitting exceptions and then resolving them, with the WikiEngine
asking for more and more...

Now it wants web.xml. How unreasonable! (and where to put it? It isn't
found in a 'WEB-INF' directory for some reason). I just want a standalone
JSPWikiMarkupParser, not the whole servlet framework. Has anyone actually
created a JSPWikiMarkupParser without the rest? or at least only a
WikiEngine? I'm kinda wondering what the minimal setup is when one doesn't
need any pages, any templates, any logs, anything except a parser...
