but how about possible confusion... you don't necessarily know if
you're comparing file 1 with file 2, or file 2 with file 1. i refer to
g_confrms, for instance, where you would like to know which structure
you're fitting onto which structure. with options '-f1' (or '-f') and
'-f2' such is immediately clear (as in the help it says 'fitting the
second structure onto the first one).
