[Tilesathome] render a region

[Ruggero]

Is it possible to develop the possibility to render an entire (little)
region with one command? For example:

./tilesGen.pl region LondonCity
./tilesGen.pl region Lombardia
./tilesGen.pl region littleregion1
...

maybe the name of the region will be defined in a local file (not an
official file in the svn), and everyone can define their region, for
example:

== my_region.dat ==

littleregion1: xy 10 20, xy 11 20, xy 12 20, xy 13 20
littleregion2: xy 30 40, xy 31 40, xy 30 41
...
medium_region: littleregion1, littleregion3
============

maybe will be better to use an xml syntax, and a tool to generate
these region.dat files
