NAME

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

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 => "WithDpkg",
           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 => 'WithDpkg' );
        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.

CONSTRUCTOR

   new ( node => $node_obj, name => 'plain_file' ) ;
       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.
