BTW, if using Getopt::Long why not also Pod::Usage?
Built-in documentation, e.g../acme.pl --help or perldoc acmel.pl. Easy to use and very handy (I'm reseller ;-)).
#!/usr/bin/perl
use warnings;
use strict;
use Getopt::Long;
use Pod::Usage;
my %options;
Getopt::Long::Configure("no_ignore_case");
GetOptions(\%options, "help", "foo=s","bar=s",);
pod2usage( -exitstatus => 0, -verbose => 2 ) if $options{help};
foreach my $option (%options ) {
pod2usage( -exitstatus => 2, -verbose => 1 ) unless $option;
}
# ...the rest.
