NAME
       Config::Model::Itself::BackendDetector - Detect available read/write backends

SYNOPSIS
	# this class should be referenced in a configuration model and
	# created only by Config::Model::Node

	my $model = Config::Model->new() ;

	$model ->create_config_class
	 (
	  name => "Test",
	  'element'
	  => [
	      'backend' => { type => 'leaf',
			     class => 'Config::Model::Itself::BackendDetector' ,
			     value_type => 'enum',
			     # specify backends built in Config::Model
			     choice => [qw/cds_file perl_file ini_file augeas custom/],

			     help => {
				      cds_file => "file ...",
				      ini_file => "Ini file ...",
				      perl_file => "file  perl",
				      custom => "Custom format",
				      augeas => "Experimental backend",
				     }
			   }
	     ],
	 );

	 my $root = $model->instance(root_class_name => 'Test') -> config_root ;

	 my $backend = $root->fetch_element('backend') ;

	 my @choices = $backend->get_choice ;

DESCRIPTION
       This class is derived from Config::Model::Value. It is designed to be used in a 'enum' value where the choice (the available backends) are
       the backend built in Config::Model and all the plugin backends. The plugin backends are all the "Config::Model::Backend::*" classes.

       This module will detect available plugin backend and query their pod documentation to provide a contextual help for config-model graphical
       editor.
