If it's useful, could make this a strict error?

[Jim Stichnoth, 2014/09/17 16:18:21]

Done.  It now computes the complete set of unknown components and prints an
error and exits if the set is non-empty.

Ideally, I would have changed the add_argument('comps', ...) line to add
choices=components, but I couldn't get it to accept zero arguments which means
use the whole list.  (Also, that makes the help message unwieldy.)
