yum erase unused dependencies

[Bill Davidsen]

I recall last year a discussion of using yum to remove unwanted packages, and 
tell it to remove only dependencies which were used by no other package. I can't 
seem to find how that was done in my notes, could someone give me a pointer to 
the method?
