If I have a command line like:

my_script.pl -foo -WHATEVER

My script knows about --foo, and I want Getopt to set variable $opt_foo, but I don't know anything about -WHATEVER. How can I tell Getopt to parse out the options that I've told it about, and then get the rest of the arguments in a string variable or a list.

An example:

use strict;
use warnings;

use Getopt::Long;

my $foo; 

GetOptions('foo' => \$foo); 

print 'remaining options: ', @ARGV;

Then, issuing

perl getopttest.pl -foo -WHATEVER

gives

Unknown option: whatever
remaining options:
