+    (description "htmlcxx is a simple non-validating CSS1 and HTML parser for
+C++.  Although there are several other HTML parsers available, htmlcxx has some
+characteristics that make it unique:
+@itemize
+@item STL like navigation of DOM tree, using excelent's tree.hh library from
+Kasper Peeters
+@item It is possible to reproduce exactly, character by character, the original
+document from the parse tree
+@item Bundled CSS parser
+@item Optional parsing of attributes
+@item C++ code that looks like C++ (not so true anymore)
+@item Offsets of tags/elements in the original document are stored in the nodes
+of the DOM tree
+@end itemize
+The parsing politics of htmlcxx were created trying to mimic Mozilla Firefox
+(https://www.mozilla.org) behavior.  So you should expect parse trees similar
+to those create by Firefox.  However, differently from Firefox, htmlcxx does
+not insert non-existent stuff in your html.  Therefore, serializing the DOM
+tree gives exactly the same bytes contained in the original HTML document.")
