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