#Clean up the tags out of the eclipse.platform.ui repo
#Probably branches as well.

# Fix R4_HEAD
# use git log -10 to find the commit, then:

#bbokowski 01abec9233ebf30c5a57f16a91d2b6edc3435dbb # parent commit

# if you are creating the main repo, you're OK
# if you haven't then you have a lot of pushing to do:
git push --force

# merge org.eclipse.ui/R4_HEAD into the 4.2 master
# did it using EGit and the http://wiki.eclipse.org/EGit/User_Guide#Resolving_a_merge_conflict
# Merge tool
    Conflicts:
        bundles/org.eclipse.ui/META-INF/MANIFEST.MF
        bundles/org.eclipse.ui/schema/viewActions.exsd
+ I had to fix PDE prefs for at least 2 projects
