+       "The libspnav library is provided as a replacement of the magellan
+library.  It provides a cleaner, and more orthogonal interface.  libspnav
+supports both the original X11 protocol for communicating with the driver, and
+the new alternative non-X protocol.  Programs that choose to use the X11
+protocol, are automatically compatible with either the free spacenavd driver
+or the official 3dxserv, as if they were using the magellan SDK.
+
+Also, libspnav provides a magellan API wrapper on top of the new API.  So, any
+applications that were using the magellan library, can switch to libspnav
+without any changes.  And programmers that are familliar with the magellan API
+can continue using it with a free library without the restrictions of the
+official SDK.")
