-libspnav - 0.2.2
-----------------
-
-1. About
-
-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.
-
-
-2. Installation
-
-Configure, make, and make install as usual.
