The GNU Tar Autoloader Patch allows you to
automate tape loading (during writing) on any
autoloader that supports changing to the next tape
with the "mt offline" command. This only has an
effect during backup. During restore, you will
still have to manually change the tape because tar
hops back and forth various times. It behaves
exactly as upstream except during a write
operation (using the "c" flag) with multiple tapes
(using the "M" flag).
