+sketching of optical experimental setups.  The package uses PSTricks for its
+output.  A wide range of free-ray and fibre components is provided, the
+alignment, positioning and labelling of which can be achieved in very simple
+and flexible ways.  The components may be connected with fibers or beams, and
+realistic raytraced beam paths are also possible.")
