+    (description
+     "Libdvdnav is a library for developers of multimedia
+applications.  It allows easy use of sophisticated DVD navigation features
+such as DVD menus, multiangle playback and even interactive DVD games.  All
+this functionality is provided through a simple API which provides the DVD
+playback as a single logical stream of blocks, intermitted by special
+dvdnav events to report certain conditions.  The main usage of libdvdnav is
+a loop regularly calling a function to get the next block, surrounded by
+additional calls to tell the library of user interaction.  The whole
+DVD virtual machine and internal playback states are completely
+encapsulated.")
