| 6 # roll_autogen.sh: Helper script for removing old revisions from an svn | |
| 7 # repository. Unfortunately, the only way to discard old revisions is to clone | |
| 8 # the repository locally, use svnadmin to dump a range of commits from the local | |
| 9 # copy, re-import them into a brand-new repository, "reset" the original repo, | |
| 10 # and then import the commits from the new repository into the original. This | |
| 11 # script automates all of that except for resetting the original repository. | |
