As the author of the only other known MPL toolkit (at least in the MPL
tree), I'm happy with the idea of using a namespace package for
mpl_toolkits. I understand your proposal to mean that each toolkit would
have a directory structure:
setup.py
lib/
mpl_toolkits/
__init__.py (empty)
basemap/
__init__.py
other_files.py
This is OK with me, but I question is whether it's necessary to have the
"lib" directory -- it seems entirely redundant. I'm fine with either
way, though.
