I feel that this is overreaction. GNU folks have reason to use
two dashes, AFAICS we do not. IMO, reasonable change would
be to replace current "catch all" item by help, that is
unrecognized option (including '--help') would print help.
Concerning '--version', it is _preferable_ to implement it
by calling 'FRICASsys' with appropriate option. ATM passing
options to 'FRICASsys' is problematic, but probably '--version'
could be done similarly to '-eval'.
