While implementing it, I found out that I don't really know how to do
it obache's way, but I do know how to do it Greg's way, so here's what
I came up with.

Put the attachment in lang/python. Then use it as follows:

In a package, set
PYTHON_PACKAGE_AUTOSWITCH=dateutil
and include
.include "../../lang/python/package_autoswitch.mk"
(better names welcome)

Comments?
