G15Composer is a scriptable command interface to the libg15render drawing 
functions that outputs to a G15daemon screen.  G15composer exposes all 
graphics primitives and text rendering functions of libg15render so that 
they may be used in a variety of situations, including from the command 
line or in virtually any scripting language. As a G15Daemon client, 
it requires that the daemon is installed and running.

This requires libg15, libg15render, and g15daemon.
