-This directory contains a sample python script implementing the Mapnik API.
-
-The script is thoroughly commented and also acts as a mini tutorial.  Reading
-it should get you on your way, and you can use it as a base for your work.
-
-You must compile and install mapnik and the python bindings FIRST.
-
-Once this is done, run it:
-
-/path/to/python rundemo.py
-
-If all goes well, it should render 2 map images:
-
-demo.jpg
-demo.png
-
-Have a look!
