However, the scenario:
1. let try the xxx package to see if it is useful
2. yum install xxx
3. yyy and zzz are installed as deps
4. ok, xxx is not that useful after all
5. yum remove xxx
6. yyy and zzz are still there

seems pretty familiar to me. I usually resort to /var/log/yum.log to
have the list of packages to uninstall...

Now I have a naive question: does it need a yet another package
database to remove, together with xxx, each package on which xxx
depends, under the constrain that xxx has to be the ONLY package
requiring it?
