docs: 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.
