Here's another suggestion. You can use Getopt and POD (plain ond documentation). All of your command line options are stored in a single hash for easy lookup. 
use strict;
use warnings;
use Getopt::Long;
use Pod::Usage;

# Process and validate the command line options in @ARGV.
my %options;
my $parse = new Getopt::Long::Parser;
if (!($parse->getoptions('infile=s',  \($options{infile}),
                         'outfile=s', \($options{outfile}),
                         'help',      \($options{help})))) {
    help();
}

if (not defined($options{infile})) {
    help();
}

sub help
{
    pod2usage(0);
}
__END__
