From here 'down' there is no concept of a commandline program, only

To make such a thing, construct an opts object with the expected
member names and values and pass it in to this method.
See the 'em_args' module and the defaults 'Parameters' implementations to
fully understand arg intake. See the 'em_cmdline' module to see how args
are taken in and how the result of the program (no exception or exception)
is translated into a return code.
