+Description: Program for computing with Groebner fans
+ 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 Groebner 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.  Among
+ these are an interactive traversal program for Groebner fans and
+ programs for graphical renderings.
+ .
+ For ordinary Groebner basis computations Gfan is not competitive in
+ speed compared to programs such as CoCoA, Singular and Macaulay2.

+.TH GFAN "1" "May 2008" "Gfan Groebner fan package   Version 0.3" "User Commands"
+.SH NAME
+Gfan \- program for computing with Groebner fans
+.SH DESCRIPTION
+This is a program for computing all reduced Groebner bases of a polynomial ideal. It takes a generating set for the ideal as input. By default the enumeration is done by an almost memoryless reverse search. If the ideal is symmetric the symmetry option is useful and enumeration will be done up to symmetry using a breadth first search. The program needs a starting Groebner basis to do its computations. If the -g option is not specified it will compute one using Buchberger's algorithm.
+
+Usage:
+.IP
+/usr/bin/gfan [options]
+
+
+
+.PP
+Options:
+.TP
+\fB\-g\fR
+Tells the program that the input is already a Groebner basis (with the initial term of each polynomial being the first ones listed). Use this option if it takes too much time to compute the starting (standard degree lexicographic) Groebner basis and the input is already a Groebner basis.
+.TP
+\fB\-\-symmetry\fR
+ Tells the program to read in generators for a group of symmetries (subgroup of $S_n$) after having read in the ideal. The program checks that the ideal stays fixed when permuting the variables with respect to elements in the group. The program uses breadth first search to compute the set of reduced Groebner bases up to symmetry with respect to the specified subgroup.
+.TP
+\fB\-e\fR
+Echo. Output the generators for the symmetry group.
+.TP
+\fB\-\-subspace\fR
+Only do breadth first search on cones with their interior intersecting a specified subspace. The subspace is given by a list of hyperplane normals at the end of the input. The intersection of the hyperplanes is the subspace being specified. Note that the set of Groebner cones intersecting the subspace could be disconnected and that only one connected component is computed. Works only together with --symmetry.
+.TP
+\fB\-\-disableSymmetryTest\fR
+When using --symmetry this option will disable the check that the group read off from the input actually is a symmetry group with respect to the input ideal.
