Unfortunately, only root can do that with yum 2.3.2 here, as user,
I get:

Python 2.4 (#1, Mar 22 2005, 21:42:42)

>>> foo.doRepoSetup()

Is that to be expected, Seth?

urlgrabber is version 2.9.6, btw..

Apart from this, yum does really nice here on SuSE 9.3 ;)

No excessive memory hogging any more like in 2.0 times, and it feels
fast, man..
