<h4>Documentation comment support</h4>

<p>Clang now supports documentation comments written in a Doxygen-like syntax.

Clang parses the comments and can detect syntactic and semantic errors in

comments. These warnings are off by default. Pass <tt>-Wdocumentation</tt>

<pre>/// \param [in] Str the string.

/// \returns a modified string.
