removing pygpgme-0.1-8.fc9.i386 b/c it is not required by anything else
removing python-iniparse-0.2.3-3.fc9.noarch b/c it is not required by
anything else

As it turns out, I personally need both of these deps.  I have a script
in ~/bin/ that uses pygpgme.  I also am working on fas in a local
checkout which requires pygpgme.  And I'm evaluating python-iniparse and
python-configobj to see which one I'm going to be using for some fedora
infrastructure scripts.

So -- I like having a script that can remove things recursively.  Even
better if I could do:
  sudo remove-recurse.py yum --exclude pygpgme

I just wouldn't want this kind of thing to be automatic or to be the
default when I do "yum remove"
