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