-# Bacula interface to mtx autoloader
-# (By Lars Köller, lars+bacula@koellers.net)
-#
-# If you set in your Device resource
-#
-# Changer Command = "path-to-this-script/chio-bacula" %c %o %S %a
-# you will have the following input to this script:
-#
-# chio-bacula "changer-device" "command" "slot" "archive-device"
-#
-# for example:
-#
-# chio-bacula /dev/sg0 load 1 /dev/nst0 (on a FreeBSD system)
-#
-# If you need to to an offline, refer to the drive as $4
-# e.g. mt -f $f offline
-#
-# Many changers need an offline after the unload. Also many
-# changers need a sleep 60 after the mtx load.
-#
-# N.B. If you change the script, take care to return either
-# the mtx exit code or a 0. If the script exits with a non-zero
-# exit code, Bacula will assume the request failed.
-#
-
-# This simulates a barcode reader in the changer.
-# The labes of the virtual barcode reader are located in the BARCODE_FILE
-SIMULATE_BARCODE=true
