+<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>
+flag to enable warnings about documentation comments.</p>
+
+<p>For example, given:</p>
+
+<pre>/// \param [in] Str the string.
+/// \returns a modified string.
+void do_something(const std::string &str);</pre>
+
+<p><tt>clang -Wdocumentation</tt> will emit two warnings:</p>
+
+<pre><b>doc-test.cc:3:6: <span class="warning">warning:</span></b> '\returns' command used in a comment that is attached to a function returning void [-Wdocumentation]
+/// \returns a modified string.
+ <span class="caret">~^~~~~~~~~~~~~~~~~~~~~~~~~~</span>
+<b>doc-test.cc:2:17: <span class="warning">warning:</span></b> parameter 'Str' not found in the function declaration [-Wdocumentation]
+/// \param [in] Str the string.
+ <span class="caret">^~~</span>
+<b>doc-test.cc:2:17: <span class="note">note:</span></b> did you mean 'str'?
+/// \param [in] Str the string.
+ <span class="caret">^~~</span>
+ <span class="caret">str</span></pre>
+
+<p>libclang includes a new API, <tt>clang_FullComment_getAsXML</tt>, to convert
+comments to XML documents. This API can be used to build documentation
+extraction tools.</p>
