Chg-juke

A shell script that uses the Fermilab "juke" software (see http://www.fnal.gov/fermitools, the "juke" link) to control tape chagners. It supports mounting multiple tapes for RAIT tapedrive sets, both multiple jukeboxes, or one jukebox with multiple tape drives, or combinations. 'juke' must be configured to know tape drives by the same name AMANDA calls them. It uses 'changerfile' to track AMANDA's current tape state, 'tapedev' must be the tape drive (or RAIT set) name, and 'changerdev' is the juke software's name for the changer, or a csh-glob that expands to several jukebox names (i.e. "changer{a,b,c}").
