Okay this is obviously just Proof code so take it as read - but grab
this script:

http://skvidal.fedorapeople.org/misc/remove-recurse.py

and run it with one arg being the pkg you wish to remove. It will print
out what it would end up doing if it was removed.

for example:

# python remove-recurse.py easytag
remove easytag
removing id3lib-3.8.3-20.fc9.i386 b/c it is not required by anything
else
removing libmp4v2-1.5.0.1-6.fc9.i386 b/c it is not required by anything
else
libmp4v2.i386 0-1.5.0.1-6.fc9 - e
id3lib.i386 0-3.8.3-20.fc9 - e
easytag.i386 0-2.1-5.fc9 - e



It doesn't actually change anything, just prints out what would happen.
then tell me which (and I'm sure there  are many) cases it doesn't
properly address.
