    <p>Simple mode that tries to handle C-like languages as well as it
    can. Takes two configuration parameters: <code>keywords</code>, an
    object whose property names are the keywords in the language,
    and <code>useCPP</code>, which determines whether C preprocessor
    directives are recognized.</p>
