and that our documentation effort still has a long way to go !

FAQ added at
http://matplotlib.sourceforge.net/faq/howto_faq.html?#how-do-i-test-whether-a-point-is-inside-a-polygon

though I am having trouble getting the module functions pnpoly and
points_inside_poly to show up in the sphinx automodule documentation
for nxutils.  These functions are defined in extension code and I have
a post in to the sphinx mailing list

  http://groups.google.com/group/sphinx-dev/t/7ad1631d3117e4eb

but if anyone on this list has seen problems with automodule and
extension code functions, and knows how to fix them, let me know.
