       Getopt::EX::Loader - RC/Module loader

	 use Getopt::EX::Loader;

	 my $loader = new Getopt::EX::Loader
	     BASECLASS => 'App::example';



	 my $parser = new Getopt::Long::Parser;
	 $parser->getoptions( ... , $loader->builtins )

       This is the main	interface to use Getopt::EX modules.  You can create
       loader object, load user	defined	rc file, load modules specified	by
       command arguments, substitute user defined option and insert default
       options defined in rc file or modules, get module defined built-in
       option definition for option parser.

       Most of work is done in "deal_with" method.  It parses command
       arguments and load modules specified by -M option by default.  Then it
       scans options and substitute them according to the definitions in rc
       file or modules.	 If RC and modules defines default options, they are
       inserted	to the arguments.

       Module can define built-in options which	should be handled option
       parser.	They can be taken by "builtins"	method,	so you should give
       them to option parser.

       If "App::example" is given as a "BASECLASS" of the loader object, it is
       prepended to all	module names.  So command line

	   % example -Mfoo

       will load "App::example::foo" module.

       In this case, if	module "App::example::default" exists, it is loaded
       automatically without explicit indication.  Default module can be used
       just like a startup RC file.

       configure name => value,	...
	       Define the name of startup file.

	       Define the base class for user defined module.  Use array
	       reference to specify multiple base classes; they	are tried to
	       be loaded in order.

	       Define the module option	string.	 String	-M is set by default.

	       Define default module name.  String default is set by default.
	       Set "undef" if you don't	want load any default module.

	       Default true, and parse module options given to "deal_with"
	       method.	When disabled, module option in	command	line argument
	       is not processed, but module option given in rc or module files
	       are still effective.

	       Default false, and process dies when given module was not found
	       on the system.  When set	true, program ignores not-existing
	       module and stop parsing at the point leaving the	argument

	   Return loaded Getopt::EX::Module object list.

	   Load	specified file.

	   Load	specified module.
