ImageConfig-Model provides a framework for validatingthe content of any configuration file or data.With a configuration model (expressed in a datastructure), Config-Model provides a tool tovalidate configuration. A graphical (Perl/Tk) or acurses interface is provided to edit configurationdata. Config-Model includes a model example forfstab and a small fstab demo.License: GNU Lesser General Public License (LGPL)Changes:
The config-edit program now supports command line arguments for changing the content of a configuration file.

DESCRIPTION

       This module is used directly by Config::Model::Node to describe a node element. This module returns a human readable string that shows the
       content of a configuration node.

       For instance (as shown by "fstab" example:

	name	     value	  type	       comment
	fs_spec      [undef]	  string       mandatory
	fs_vfstype   [undef]	  enum	       choice: auto davfs ext2 ext3 swap proc iso9660 vfat ignore, mandatory
	fs_file      [undef]	  string       mandatory
	fs_freq      0		  boolean
	fs_passno    0		  integer

       This module is also used by the "ll" command of Config::Model::TermUI.

CONSTRUCTOR

       No parameter. The constructor should be used only by Config::Model::Node.
