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