      <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>
