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> | ||
