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 type value comment fs_spec string [undef] mandatory fs_vfstype enum [undef] choice: auto davfs ext2 ext3 swap proc iso9660 vfat ignore, mandatory fs_file string [undef] mandatory fs_freq boolean 0 fs_passno integer 0
This module is also used by the "ll" command of Config::Model::TermUI.
No parameter. The constructor should be used only by Config::Model::Node.
Return a description string.
Parameters are:
describe => ( pattern => qr/^foo/ )
