NAME

       AppConfig::Getopt - Perl5 module for processing command line arguments via delegation to Getopt::Long.

SYNOPSIS

	   use AppConfig::Getopt;

	   my $state  = AppConfig::State->new(\%cfg);
	   my $getopt = AppConfig::Getopt->new($state);

	   $getopt->parse(@args);	      # read args

OVERVIEW

       AppConfig::Getopt is a Perl5 module which delegates to Johan Vroman's Getopt::Long module to parse command line arguments and update values
       in an AppConfig::State object accordingly.

       AppConfig::Getopt is distributed as part of the AppConfig bundle.

DESCRIPTION

   USING THE AppConfig::Getopt MODULE
       To import and use the AppConfig::Getopt module the following line should appear in your Perl script:

	   use AppConfig::Getopt;

       AppConfig::Getopt is used automatically if you use the AppConfig module and create an AppConfig::Getopt object through the getopt() method.

       AppConfig::Getopt is implemented using object-oriented methods.	A new AppConfig::Getopt object is created and initialised using the new()
       method.	This returns a reference to a new AppConfig::Getopt object.  A reference to an AppConfig::State object should be passed in as the
       first parameter:

	   my $state  = AppConfig::State->new();
	   my $getopt = AppConfig::Getopt->new($state);

       This will create and return a reference to a new AppConfig::Getopt object.

   PARSING COMMAND LINE ARGUMENTS
       The "parse()" method is used to read a list of command line arguments and update the state accordingly.

       The first (non-list reference) parameters may contain a number of configuration strings to pass to Getopt::Long::Configure.  A reference to
       a list of arguments may additionally be passed or @ARGV is used by default.

	   $getopt->parse();			   # uses @ARGV
	   $getopt->parse(@myargs);
	   $getopt->parse(qw(auto_abbrev debug));  # uses @ARGV
	   $getopt->parse(qw(debug), @myargs);

       See Getopt::Long for details of the configuartion options available.

       A Getopt::Long specification string is constructed for each variable defined in the AppConfig::State.  This consists of the name, any
       aliases and the ARGS value for the variable.

       These specification string are then passed to Getopt::Long, the arguments are parsed and the values in the AppConfig::State updated.

       See AppConfig for information about using the AppConfig::Getopt module via the getopt() method.
