NAME
       Config::Model::Backend::ShellVar - Read and write config as a "SHELLVAR" data structure

VERSION
       version 2.021

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

	my $model = Config::Model->new;
	$model->create_config_class (
	   name    => "MyClass",
	   element => [
	       [qw/foo bar/] => {qw/type leaf value_type string/}
	   ],

	  read_config  => [
	       {
		   backend => 'ShellVar',
		   config_dir => '/tmp',
		   file  => 'foo.conf',
		   auto_create => 1,
	       }
	   ],
	);

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

	$root->load('foo=FOO1 bar=BAR1' );

	$inst->write_back ;

       File "foo.conf" now contains:

	## This file was written by Config::Model
	## You may modify the content of this file. Configuration
	## modifications will be preserved. Modifications in
	## comments may be mangled.
	##
	foo="FOO1"

	bar="BAR1"

DESCRIPTION
       This module is used directly by Config::Model to read or write the content of a configuration tree written with "SHELLVAR" syntax in
       "Config::Model" configuration tree.

       Note that undefined values are skipped for list element. I.e. if a list element contains "('a',undef,'b')", the data structure will contain
       'a','b'.

CONSTRUCTOR
   new ( node => $node_obj, name => 'shellvar' ) ;
       Inherited from Config::Model::Backend::Any. The constructor will be called by Config::Model::AutoRead.

   read ( io_handle => ... )
       Of all parameters passed to this read call-back, only "io_handle" is used. This parameter must be IO::File object already opened for read.

       It can also be undef. In this case, "read()" will return 0.

       When a file is read,  "read()" will return 1.

   write ( io_handle => ... )
       Of all parameters passed to this write call-back, only "io_handle" is used. This parameter must be IO::File object already opened for
       write.

       "write()" will return 1.
