Tag the current ERASER branch, checkout a fresh copy off the HEAD
branch, merge your changes from the new ERASER tag into your working
copy.  If you have any conflicts from development done on the HEAD
branch after the ERASER branch started either resolve them, or to
discard them merge from the new tag on ERASER onto the tag from the
beginning of the branch.  Commit those changes and move on in the HEAD
branch, leaving the ERASER branch to wither on the vine, to extend the
metaphor.  The developers will need to checkout a new copy to get back
onto the HEAD branch.

It would be a good idea to include a nice, verbose comment in the commit
to the HEAD branch detailing the exact steps you took so months later if
a commit turns up missing you have something to start with.
