To build docs ....
* install sphinx from svn.
* make _static and sphinxext symlinks here that point to the corresponding
directories in the matplotlib doc tree, e.g.
ln -s ../../../matplotlib/doc/_static _static
ln -s ../../../matplotlib/doc/sphinxext sphinxext
* copy matplotlibrc to users/figures, edit to make default figure size 6,6
instead of 8,6.
* run 'python make.py html'. Entry point is build/html/index.html.
* to update on sf site:
cd build
rsync -avz html jswhit,matplotlib@web.sf.net:/home/groups/m/ma/matplotlib/htdocs/basemap/doc/ -essh
