Usage: $ME [options] [-- script options]
(shielding $EXEC)
molly-guard's primary goal is to guard against accidental
shutdowns/reboots. $ME will run all scripts in $SCRIPTSDIR and only
invokes $EXEC if all scripts exited successfully.
Specifying --molly-guard-do-nothing as argument to the command will
make $ME echo the command it would execute rather than actually
executing it.
Options following the double hyphen will be passed unchanged to the
scripts.
Please see molly-guard(8) for more information.
The actual command's help output follows:
_eousage
