# 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.
