-# This assumes we have possibly rait-striped drives in several
-# jukeboxes, controlled by the Fermilab "juke" package
-#
-# So we could have 3 drives in 3 jukeboxes:
-# changerscript="chg-juke"
-# changerfile=/some/file
-# tapedev="rait:/dev/nst{1,2,3}"
-# changerdev="myjuke{0,1,2}"
-# Or, if the jukebox has multiple drives:
-# changerscript="chg-juke"
-# changerfile=/some/file
-# tapedev="rait:/dev/nst{1,2,3}"
-# changerdev="myjuke"
-# We need therefore to generate lists with csh to expand the tapedev
-# and changerdev, and deal with the possibility that there are several
-# jukeboxes and several drives in each jukebox involved.
