NAME
       Config::Model::Backend::PlainFile - Read and write config as plain file

VERSION
       version 2.021

SYNOPSIS
	use Config::Model;
	use Log::Log4perl qw(:easy);
	Log::Log4perl->easy_init($WARN);

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

	my $inst = $model->create_config_class(
	   name => "WithPlainFile",
	   element => [
	       [qw/source new/] => { qw/type leaf value_type uniline/ },
	   ],
	   read_config	=> [
	       {
		   backend => 'plain_file',
		   config_dir => '/tmp',
	       },
	   ],
	);

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

	$root->load('source=foo new=yes' );

	$inst->write_back ;

       Now "/tmp" directory will contain 2 files: "source" and "new" with "foo" and "yes" inside.

DESCRIPTION
       This module is used directly by Config::Model to read or write the content of a configuration tree written in several files.  Each element
       of the node is written in a plain file.

       This module supports currently only leaf and list elements.  In the case of "list" element, each line of the file is a value of the list.

Methods
   read_leaf (obj,elt,check,file,args);
       Called by read method to read the file of a leaf element. "args" contains the arguments passed to read method.

   read_hash (obj,elt,check,file,args);
       Like read_leaf for hash elements.

   read_list (obj,elt,check,file,args);
       Like read_leaf for list elements.

   write ( )
       "write()" will write a file for each element of the calling class. Works only for leaf and list elements. Other element type are skipped.
       Always return 1 (unless it died before).
