-DRAWxtl is a program to display crystal structures on ordinary computer hardware
-and operating systems. Four forms of graphics are produced:
-(1) an openGL window for immediate viewing,
-(2) the Persistence of Vision Ray Tracer (POV-RAY) scene language for
-    publication-quality drawings, (3) the Virtual Reality Modeling Language
-    (VRML) for dissemination across the Internet, and
-(4) a Postscript rendering of the OpenGL window for those that want high-quality
-    output but do not have POV-RAY installed.
