There is none.  The hush shell was copied from the busybox project
(and I have to admit that I don't know where they got it from).
Bysybox does not document it's use either...

This is a silly note when posting to a public mailing list,  Please
switch this off.  If this is not possible from the account you are
using, then please consider using a free account without such
nonsense footers when posting to public lists.

Thanks.

Best regards,
