surf-alggeo-nox binary package in Ubuntu Lunar s390x

 Surf is a script driven tool to visualize some real algebraic geometry:
 plane algebraic curves, algebraic surfaces and hyperplane sections of
 surfaces.
 .
 The algorithms should be stable enough not to be confused by curve/surface
 singularities in codimension greater than one and the degree of the surface
 or curve. This has been achieved quite a bit. Curves of degree up to 30 and
 surfaces of degree up to 20 have been drawn successfully. However, there are
 examples of curves/surfaces of lower degree where surf fails to produce
 perfect images. This happens especially if the equation of the curve/surface
 is not reduced. Best results are achieved using reduced equations. On the other
 hand, surf displays the Fermat-curves accurately for degree up to 98.
 .

 This package provides the script driven tool surf without X support.
