<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>
<p><strong>MIME types defined:</strong> <code>text/x-csrc</code>
(C), <code>text/x-c++src</code> (C++), <code>text/x-java</code>
(Java), <code>text/x-csharp</code> (C#),
<code>text/x-objectivec</code> (Objective-C),
<code>text/x-scala</code> (Scala), <code>text/x-vertex</code>
and <code>x-shader/x-fragment</code> (shader programs).</p>
