#
#	This changer script is based on a directory structure like:
#	slot_root_dir -|
#	               |- info
#	               |- data -> slot1
#	               |- slot1
#	               |- slot2
#	               |- ...
#	               |- slotn
#	where 'slot_root_dir' is the tapedev 'file:xxx' parameter and 'n'
#	is the LASTSLOT value of your changerfile config file. If LASTSLOT is
#	not defined, the value of the tapecycle parameter is used.
#
#	To use this driver, just put the line 'tpchanger "chg-disk"' in your
#	amanda.conf.
#
#	Example of use (amanda.conf):
#	--- cut here ---
#	tapedev  "file:/BACKUP2/slots/"
#	changerdev "/dev/null"
#	changerfile "chg-disk"
#	tpchanger "chg-disk"
#	changerfile "/usr/local/amanda/etc/changer"
#	tapetype HARD-DISK
#	define tapetype HARD-DISK {
#	    length 12000 mbytes
#	}
#	--- cut here ---
#
#	Example changerfile (chg-disk.conf):
#	--- cut here ---
#	LASTSLOT=12
#	--- cut here ---
#
#	The number of slot is equal to your LASTSLOT or tapecycle.
#	You must create the slots and data directory.
