+  <description>Libxml2 is the XML C parser and toolkit developed for the Gnome
+project (but usable outside of the Gnome platform), it is free software
+available under the MIT License. XML itself is a metalanguage to design markup
+languages, i.e. text language where semantic and structure are added to the
+content using extra "markup" information enclosed between angle brackets. HTML
+is the most well-known markup language. Though the library is written in C a
+variety of language bindings make it available in other environments.
+
+Libxml2 is known to be very portable, the library should build and work
+without serious troubles on a variety of systems (Linux, Unix, Windows,
+CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, VxWorks,
+...)</description>
