- # fixgusidir - Modify filenames in the CWGUSI source tree, so
- # that it can be put under CVS. Needed because there are files with slashes
- # in their name, which CVS does not approve of.
- #
- # Usage:
- # - On importing gusi in cvs:
- # - Run the script after unpacking the gusi distribution. This creates
- # _s_ files for all / files.
- # - Remove all / files with "find file" or some such.
- # - import the tree
- # - On checking out gusi:
- # - After checkout, run the script to create / files for all _s_ files.
- # - After modifying stuff, or later checkouts:
- # - Run the script. Conflicts between / and _s_ files will be reported.
- # - Fix the problems by removing the outdated / or _s_ file.
- # - Run the script again. Possibly do a cvs checkin.
