Syntax:
autobind <item> -force

The 'autobind' command is used to permanently bind certain types of
equipment to a character or to an account.  Items bound to a player
can only be used by the player.  Items bound to an account can only
be used by that account.

In order to transfer a bound item to another player or account, you
must 'unbind' it first.  See 'help unbind' and 'credit buy unbind'
for information on how to unbind equipment.

Note that autobinding is generally required for extremely old,
extremely powerful historical equipment.
