NURBS is not a package (well maybe it is but I've never heard of it) but stands
for: Non-Uniform Rational B-Splines.  These are now available from the graphics
library.

Here are the available on-line man pages:
bgnsurface, endsurface (3G) - delimit a NURBS surface definition
bgntrim, endtrim (3G)   - delimit a NURBS surface trimming loop
getnur (3G)             - returns the current value of a trimmed NURBS surfaces 
display property
getnurbsproperty (3G)   - returns the current value of a trimmed NURBS surfaces 
display property
nurbscurve (3G)         - controls the shape of a NURBS trimming curve
nurbssurface (3G)       - controls the shape of a NURBS surface
pwlcurve (3G)           - describes a piecewise linear trimming curve for NURBS 
surfaces
setnur (3G)             - sets a property for the display of trimmed NURBS surfa
ces
setnurbsproperty (3G)   - sets a property for the display of trimmed NURBS surfa
ces
trimnurbs (1)           - create, display and edit trimmed, non-uniform, rationa
l B- Spline surfaces (NURBS)
