    <p>Simple mode that tries to handle C-like languages as well as it

    can. Takes two configuration parameters: <code>keywords</code>, an

    object whose property names are the keywords in the language,
 | 
						|
    and <code>useCPP</code>, which determines whether C preprocessor
 | 
						|
    directives are recognized.</p>
