SYNOPSIS

        zmu -d device_path [-v] [function] [-U<username> -P<password>]
        zmu --device device_path [-v] [function] [-U<username> -P<password>]

        zmu --monitor monitor_id [-v] [function] [-U<username> -P<password>]

DESCRIPTION

       This binary is a handy command line interface to several useful functions. It's not really
       meant to be used by anyone except the web page (there's only limited 'help' in it so far)
       but can be if necessary, especially for debugging video problems.
