Description:

TileCache is a BSD licensed tile caching mechanism. The goal is
to make it easy to set up a WMS or TMS front-end to any back-end
data services you might be interested in, using a pluggable
caching and rendering mechanism.

TileCache was developed by MetaCarta Labs as a companion to OpenLayers.
This TileCache client supports multiple different rendering back-ends
(Mapserver, Mapnik etc). Each rendering back-end also supports the
ability to draw 'meta-tiles', where a large tile is rendered, and then
chopped into smaller tiles using the Python Imaging library.
