Since there are various ongoing requests for this from the sites, I have moved all of our custom MEDM screens into the cds_user_apps SVN repository. This is what I did:
For each system in /opt/rtcds/caltech/c1/medm, I copied their "master" directory into the repo, and then linked it back in to the usual place, e.g.:
mv $a $b
ln -s $b $a
Before committing to the repo, I did a little bit of cleanup, to remove some binary files and other known superfluous stuff. But I left most things there, since I don't know what is relevant or not.
Then committed everything to the repo.
