Single dash is widely used for options. The main reason for
double dash was that folks wanted to add new options that
did not fit existing single dash usage. Nobody sane wants
to remove single dash options from existing programs, so to
allow co-existence double dash is used. We do not have
such problem, our single dash options have room for expansion.
Concerning expectation, people who actually use options
will expect single dash options. Simple reason to prefer
single dash is that it is shorter. Another is that this
is what we use. Change would introduce confusion.
Note: '--version' is somewhat special and it is new, so
double dash is reasonable here (however, using '-version'
would be reasonable too).

AFAICS you do not implement passing options to 'FRICASsys'. You
use existing hack... That I call problematic (but for now
it must do).
