Every module derived from lib.Cmd implements its own parser.add_argument() logic. As a consequence, all Cmd derived modules need to be loaded to have the full argument tree available. This is avoided during normal program startup because it takes some time. It's not necessary during normal program execution, nor for showing help messages. It is, however, needed for argcomplete to do its thing, so fully parse the command line if the program runs in argcomplete mode, as determined by checking if _ARGCOMPLETE is present in the environment.
