DESCRIPTION

       This module is used directly by Config::Model::Node to provide a human readable report of
       the configuration. This report includes the configuration values and (if provided by the
       model) the description of the configuration item and their effect.

       A "report" will show "all" configuration items. An "audit" will show only configuration
       items which are different from their default value.

CONSTRUCTOR

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

Methods

   report
       Returns a string containing the configuration values and (if provided by the model) the
       description of the configuration item and their effect.

       Parameters are:

       audit
           Set to 1 to report only configuration data different from default values. Default is
           0.

       node
           Reference to the Config::Model::Node object that is dumped. All nodes and leaves
           attached to this node are also dumped.
