The script /afs/slac.stanford.edu/package/java/build/release is a bourne shell script that assembles the names of the volumes in the java directory that will be updated and then makes calls to the vos_release command which in turn calls vos commands to update a release. The same script is in the shadow directory but it refers to the visible path when building the package list. If you make changes to the installation then rerun the script to pick up the changes.
