-# roll_autogen.sh: Helper script for removing old revisions from an svn
-# repository.  Unfortunately, the only way to discard old revisions is to clone
-# the repository locally, use svnadmin to dump a range of commits from the local
-# copy, re-import them into a brand-new repository, "reset" the original repo,
-# and then import the commits from the new repository into the original.  This
-# script automates all of that except for resetting the original repository.
