┌─ Usage ───────────────────────────────────────────────────────────────────────┐
│• usbrestore creates the restore.autorun file on the root of your USB volume   │
│• restore.autorun runs atomatically at the next reboot (once only)             │
│• If usbrestore is not defined the script nvram_backup prints out to stout     │
│• The erase option adds a "nvram erase" at the top of the restore script         │
│• to redirect the config to a file just use nvram_backup \$par1 \$par2 ... >file │
│• mac is needed only in certain cases like WDS, wl_hw same device restore only │
