 Gfan is a software package for computing Groebner fans and tropical
-varieties. These are polyhedral fans associated to polynomial ideals.
-The maximal cones of a Groebner fan are in bijection with the marked
-reduced Groebner bases of its defining ideal. The software computes
-all marked reduced Groebner bases of an ideal. Their union is a
-universal Greobner basis. The tropical variety of a polynomial ideal
-is a certain subcomplex of the Groebner fan. Gfan contains algorithms
-for computing this complex for general ideals and specialized
-algorithms for tropical curves, tropical hypersurfaces and tropical
-varieties of prime ideals.  In addition to the above core functions
-the package contains many tools which are useful in the study of
-Groebner bases, initial ideals and tropical geometry.
+varieties.
 
-This port provides only the static library libgfan.a: you can get the
-rest of the software package from the port math/gfan.
