+# Bacula interface to chio(1) autoloader for OpenBSD
+#
+# Adapted from NetBSD pkgsrc and examples/autochangers in bacula source)
+# by Antoine Jacoutot <ajacoutot@openbsd.org> for OpenBSD.
+# Tested on an LTO-4 device with 8 slots.
+# The user Bacula is running as needs rw access to the ch(4) and st(4)
+# devices.
+#
+# If you set in your Device resource:
+#      Changer Command = "/path/to/chio-changer-openbsd %c %o %S %a %d"
+# you will have the following input to this script:
+#      chio-changer-openbsd "changer-device" "command" "slot" "archive-device" "drive-index"
+#                            $1               $2        $3     $4               $5
+#
+# So Bacula will always call with all the following arguments, even though
+#     in come cases, not all are used.
+#
+# N.B. If you change the script, take care to return either 
+#      the chio exit code or a 0. If the script exits with a non-zero
+#      exit code, Bacula will assume the request failed.
