Pod::Usage::CommandLine - Add some common command line options from Pod::Usage
use Pod::Usage::CommandLine; BEGIN { our $VERSION = '1.0'; } # NOTE: Set main version in BEGIN block # then, use command line options: my_program.pl --version my_program.pl --help my_program.pl -h my_program.pl '-?' my_program.pl --man my_program.pl -m # You can also export GetOptions and/or pod2usage if you need them: use Pod::Usage::CommandLine qw(GetOptions pod2usage); my %opt; GetOptions(\%opt, @getopt_long_specs) or pod2usage;
Basically a cut/paste from the boilerplate described in Pod::Usage and Getopt::Long so it can be included with a single "use" instead of cut/pasting it.
See Getopt::Long for all the intricacies of specifying options.
Set $VERSION in a BEGIN block as shown above so it will get picked up by the '--version' option.
GetOptions and pod2usage are exported on demand.
GetOptions
pod2usage
