Perl Quick Start Template

When starting a new script, you can use this template as a base which consists of:

1. RCS, CVS or SVN "Id" keyword to keep the version information.
2. Support script arguments.
3. Show usage function.
4. A trim function.

#!/usr/bin/perl -w
# $Id: $
#
use strict;
use Getopt::Long;

my $VERSION = "1.0";

my %option;
die unless GetOptions(
    "help"         => \$option{'help'},
);

if (defined( $option{'help'} )) {
    print_usage();
}

...


# Perl trim function to remove whitespace from the start and end of the string
sub trim {
    my $string = shift;
    $string =~ s/^\s+//;
    $string =~ s/\s+$//;
    return $string;
}

# Print usage
sub print_usage {
    my $usage = <<EOF;
DESCRIPTION:
