NAME

       AppConfig::Std - subclass of AppConfig that provides standard options

SYNOPSIS

           use AppConfig::Std;

           $config = AppConfig::Std->new();

           # all AppConfig methods supported
           $config->define('foo');            # define variable foo
           $config->set('foo', 25);           # setting a variable
           $val = $config->get('foo');        # getting variable
           $val = $config->foo();             # shorthand for getting

           $config->args(\@ARGV);             # parse command-line
           $config->file(".myconfigrc")       # read config file

DESCRIPTION

       AppConfig::Std is a Perl module that provides a set of standard configuration variables and command-line
       switches.  It is implemented as a subclass of AppConfig; AppConfig provides a general mechanism for
       handling global configuration variables.

       The features provided by AppConfig::Std are:

       •   Standard command-line arguments: -help, -doc, -version, -verbose, and -debug. AppConfig::Std handles
           the -help, -doc, and -version switches for you, so you don't need to duplicate that code in all of
           your scripts.  These are described below.

       •   The ARGCOUNT default is set to 1. This means that by default all switches are expected to take a
           value. To change this, set the ARGCOUNT parameter when defining the variable:

               $config->define('verbose', { ARGCOUNT => 0 } );

       Please read the copious documentation for AppConfig to find out what else you can do with this module.

STANDARD OPTIONS

       The module adds five standard configuration variables and command-line switches. You can define
       additional variables as you would with AppConfig.

   HELP
       The -help switch will result in a short help message.  This is generated using Pod::Usage, which displays
       the OPTIONS section of your pod. The script will exit with an exit value of 0.

   DOC
       The -doc switch will result in the entire documentation being formatted to the screen.  This is also done
       with Pod::Usage.  The script will exit with an exit value of 0.

   VERSION
       The -version switch will display the version of the invoking script.  This assumes that you have defined
       $VERSION in your script with something like the following:

           use vars qw( $VERSION );
           $VERSION = sprintf("%d.%02d", q$Revision: 1.7 $ =~ /(\d+)\.(\d+)/);

       The script will exit with an exit value of 0.

   DEBUG
       The -debug switch just sets the debug variable.  This is useful for displaying information in debug mode:

           $foobar->dump() if $config->debug;

   VERBOSE
       The -verbose switch just sets the verbose variable.  This is useful for displaying verbose information as
       a script runs:

           print STDERR "Running foobar\n" if $config->verbose;

TODO

       Please let me know if you have ideas for additional switches, or other modifications. Things currently
       being mulled:

       •   Support brief switches, such as -h as well as -help.  This could be a config option for the
           constructor.

       •   Include a sample script called mkscript, which would create a template script along with Makefile.PL,
           MANIFEST, etc.  Kinda of a h2xs for scripts.

EXAMPLE

       The following is the outline of a simple script that illustrates use of the AppConfig::Std module:

           #!/usr/bin/perl -w
           use strict;
           use AppConfig::Std;

           use vars qw( $VERSION );
           $VERSION = '1.0';

           my $config = AppConfig::Std->new();

           # parse command-line and handle std switches
           $config->args(\@ARGV);

           exit 0;

           __END__

           standard pod format documentation

       The pod documentation is expected to have the NAME, SYNOPSIS, DESCRIPTION, and OPTIONS sections. See the
       documentation for "pod2man" for more details.

       available from CPAN.

       Pod::Usage - Brad Appleton's module for extracting usage information out of a file's pod. This is used
       for the -doc and -help switches.  Available from CPAN as part of the PodParser distribution.

       AppConfig::Std uses Pod::Usage, which assumes well-formed pod.
