New submission from Tres Seaver <tseaver@palladion.com>:

When running 'python setup.py develop', it would be useful to install one (=
or
more) of the 'extra' requirements for the package-under-development.  The
attached patch allows installing one at a time:  I don't have the options f=
u to
make it a repeatable option.
