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