        Parameters
        ----------
        cp : WorkflowConfigParser
            Config file parser to read.
        section : str
            The name of the section to read.
        skip_args : list of str, optional
            Names of arguments to skip.
        dtypes : dict, optional
            A dictionary of arguments -> data types. If an argument is found
            in the dict, it will be cast to the given datatype. Otherwise, the
            argument's value will just be read from the config file (and thus
            be a string).

        Returns
        -------
        dict
            Dictionary of keyword arguments read from the config file.
