Description:
 def get_cmd_description(self):
 """ Get the leading, multi-line description of this command. :returns: ``self.description``, if defined :returns: A substring of the class docstring between the first line (which is discarded) and the string ``@EPILOG@``, if present, or the end of the docstring, if any :returns: None, otherwise The description string will be displayed after the usage string but before any of the detailed argument descriptions. Please consider following good practice by keeping the description line short enough not to require scrolling but useful enough to provide additional information that cannot be inferred from the name of the command or other arguments. Stating the purpose of the command is highly recommended. """
