DESCRIPTION

46       This class is derived from Config::Model::Value. It is designed to be
47       used in a 'enum' value where the choice (the available backends) are
48       the backend built in Config::Model and all the plugin backends. The
49       plugin backends are all the "Config::Model::Backend::*" classes.
50
51       This module will detect available plugin backend and query their pod
52       documentation to provide a contextual help for config-model graphical
53       editor.
