[Tilecache] Use of tileCache with Mapnik

[Dane Springmeyer]

Arnaud,

Great, good to hear. I'm about to commit a change to Mapnik so that  
that relative paths are interpreted based on the working directory of  
the XML file (https://trac.mapnik.org/ticket/326), which should make  
it easier to use relative paths with a TileCache process in the future.

Also, of interest to TileCache users, Mapnik trunk now supports 8-bit  
PNG transparency.
