Remove unused dependencies?

[sheep]

Ok .. so you want to install program "x" which draws deps a, b and c. Later on you decide to remove program "x" from your system. You do it. Assuming nothing else uses a, b and c you now have some programs installed for no good reason. Is there a way to remove all "unused dependencies"?

Try 'yum deplist programname' (see 'man yum'). You can then check out which dependencies accompany a program and choose whether to remove them.
