Something like this might be an option:

#!/usr/bin/env perl

use strict;
use warnings;
use Getopt::Long;
use Data::Dump;

my $action = shift;
my %options;
my %actions = ( nose => \&nose, cuke => \&cuke );

$actions{$action}->();

dd \%options;

sub nose { GetOptions( \%options, "foo=s" ) }
sub cuke { GetOptions( \%options, "bar=s" ) }

OK, very simplified to get the idea. See also Re: GetOpt Organization.

Update: In other words: Make your program behave like aptitude. At least a bit.
