This version implements automatic support for --version and --help
options. You are invited to try it out and feedback.
**************** WARNING -- EXPERIMENTAL CODE AHEAD ****************
* Getopt::Long will automatically provide --version and --help options
if the call to GetOptions did not specify them explicitly. Since
this is a non-compatible API change, the new features will only be
available to programs that explicitly require version 2.3203 or
later.
Getopt::Long uses module Pod::Usage to produce the help message from
the SYNOPSIS section of the program's POD.
Two subroutines can be exported on demand:
- VersionMessage
This subroutine prints the standard version message.
- HelpMessage
This subroutine prints the standard help message.
Both subroutines take the same arguments as Pod::Usage::pod2usage,
see its documentation for details.
Example:
use Getopt::Long 2.3203 qw(GetOptions HelpMessage);
GetOptions(...) or HelpMessage(2);
Using a --help (or -?) command line option will write the SYNOPSIS
section of the program's POD to STDOUT, and exit with status 0.
However, an illegal option will produce the help text to STDERR,
and exit with status 2. This is in accordance with current
conventions.
**************** END EXPERIMENTAL CODE ****************
Happu hacking,
