Is there an easy way to have this run on demand via a webscript, I've
tried to call it via php and keep getting:

Step: 4 // --> Loaded XML from string
XML document not well formed

It works fine if I run it from the command line, and the php script
can read the xml/mapnik style sheet file I'm telling nik2img to use.
