+This directory contains demos that use the Panel Library by NASA Ames.
+They only run on SGI machines and require the 'pnl' and 'gl' built-in
+modules. Each subdirectory contains one demo.
+
+apanel A trivial user interface to the audio capabilities of
+ the 4D/25 (Personal IRIS). Lets you record a sample and
+ play it back at different volumes. Requires the 'audio'
+ built-in module.
+
+flying A large demonstration that can display several
+ differently shaped objects through space. Control
+ panels let you manipulate light sources, material
+ properties and drawing modes.
+
+nurbs A demo of the capabilities of the GL 'nurbs' functions
+ that can display the control points. (It was intended
+ to let you move these as well, but there was a problem
+ with the mapping of mouse movements in a 3-D world.)
+
+twoview A demo of GL's transformation primitives. Two views on
+ a scene are given, and the position and orientation of a
+ viewer in one of the views can be changed through
+ various buttons and dials in a control panel.
