%description
The software computes all marked reduced Gröbner bases of an ideal.
Their union is a universal Gröbner basis. 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 Gröbner bases,
initial ideals and tropical geometry. Among these are an interactive
traversal program for Gröbner fans and programs for graphical renderings.
