UGCS Software

We've written many small pieces of software to help make our cluster run or to help our users have a better experience. Most of it is in our svn repository at file:///afs/ugcs.caltech.edu/ugcs-admin/svn or http://www.ugcs.caltech.edu/svn (read-only web)

Although we've tried to write as much of this software as generically as possible, it may still contain specific UGCS references. If you have any questions (or are using it successfully!), let us know
