Here is an example on how to use it::
>>> from mapnik import Projection, Coord
>>> p = Projection('+init=epsg:27700') # British National Grid
>>> p.forward(Coord(-1.125,51.75))
>>> import mapnik
>>> p = mapnik.Projection('+init=epsg:27700') # British National Grid
>>> p.forward(mapnik.Coord(-1.125,51.75))
Coord(460396.920899,206113.214203) # reprojected coordinate x, y pair
>>> p.forward(Envelope(-1.125,51.75,-1.0,50.75))
>>> p.forward(mapnik.Envelope(-1.125,51.75,-1.0,50.75))
