Hello all,

I looked around everywhere for a script that could make it easy for me 
to store stale branches in refs/attic for possible later retrieval.  I 
don't like such branches lying around in refs/heads and used to tag them 
to clear them out of the way, but then that makes "git push origin 
--tags" unusable, since I don't want to push my stale branches out...

Anyway, I wrote my own little script in the end and thought it might be 
useful to others.

Please Cc pdgiddie@gmail.com in replies,
