usage: git rm-conflicts ours|theirs FILES...

With 'ours', delete conflicts coming from the current branch (aka HEAD).
With 'theirs', delete conflicting code from the commits you're trying to
merge in.

Example:
  $ git checkout master
  $ git merge foo
    <lots of conficts from foo I don't care about>
  $ git rm-conflicts ours FILE1 FILE2
    <delete conflicts in FILE1 and 2, but check the others>

NOTE: You almost never want to use this command, but instead should
check why exactly your files are conflicting.  Use of this script is
almost guaranteed to throw away code you don't want to throw away!!
But if you need it, here it is.
