Removal of dupe packages with yum

[PFJ]

Hi,

I remember seeing something on this (or one of the other FC lists) a
couple of days back which gave a really neat way of getting yum to
remove all dupes automagically, but can't for the life of me find it in
the archives.

If anyone has it handy (or has the URL), can you let me know? My laptop
seems somewhat cluttered!

TTFN
