Perl :: Getopt::Long in the program

While going through some of the perl script...

I had found the below line..
Code:
use Getopt::Long;
my $GetOptionsReturnCode = GetOptions (      '<>' => sub { push(@unknownArg, @_);  },    'h|help' => sub {  &helpMessage();  exit 0; },   );

Could anyone please explain the above one ...
