+cat << EOF
+Gfan is a software package for computing Gröbner fans and tropical varieties. 
+These are polyhedral fans associated to polynomial ideals. The maximal cones of
+a Gröbner fan are in bijection with the marked reduced Gröbner bases of its 
+defining ideal. The software computes all marked reduced Gröbner bases of an 
+ideal. Their union is a universal Gröbner basis. The tropical variety of a 
+polynomial ideal is a certain subcomplex of the Gröbner fan.
