-# This changer script controls tape libraries on operating systems that have a
-# chgio program
-# DSL 7000 on FreeBSD is an example
-#
-# The changer being used is a n tape juke, that can be used with 1, n-1 or n
-# tapes in the juke. The special slot is slot n. The script does not
-# make assumptions about the number of slots, except that the special slot
-# is the highest number. The slot is special in the sense that it contains the
-# the only tape if the juke contains 1 tape and contains no tape if the juke
-# contains n-1 tapes. See getCurrentTape.
-#
-# Furthermore, the script uses drive 0 and assumes that the device is able to
-# figure itself how to move a type from slot m to drive 0 if asked to do so and
-# multiple pickers are present.
-#
-# The numbering of the slots is by the way from 1 to n with slots. The chio
-# program returns the slot numbers numbered from 0 to n-1 however.
-#
-# This script is built up out of bits and pieces of the other scripts
-# and no credits are claimed. Most notably the chg-rth.pl script was used. That
-# script was written by Erik Frederick, <edf@tyrell.mc.duke.edu>.
-#
-# Permission to freely use and distribute is granted (by me and was granted by
-# the original authors).
