LibGII is an input library developed by the GGI Project
(http://www.ggi-project.org). Its design philosophy is similar to
LibGGI, which deals with graphics output.

LibGII is based on the concept of input streams, which virtualize
access to the underlying input drivers. Events from various input
devices are abstracted into easy-to-use structures. LibGII also allows
the application to join streams together, receiving input from an
arbitrary combination of devices.

LibGII is a separate component from LibGGI, although LibGGI depends on
LibGII for input purposes. (LibGGI's input functions are simply
wrappers for LibGII functions.)
