# TESTING NOTE: "make test" does not work, because the test drivers are not
# distributed with the released sources.  A Subversion repository containing
# all of the sources, including the test drivers, was made available recently.
# Once the next release of polymake occurs, we will extract the necessary test
# drivers from subversion and produce a check script.

# Release candidates are sometimes promoted to release without removing the tag

%description
Polymake is a tool to study the combinatorics and the geometry of convex
polytopes and polyhedra.  It is also capable of dealing with simplicial
complexes, matroids, polyhedral fans, graphs, tropical objects, and so
forth.

Polymake can use various computational packages if they are installed.
Those available from Fedora are: 4ti2, azove, gfan, latte-integrale,
normaliz, ocaml-tplib-tools, qhull, Singular, TOPCOM, and vinci.

Polymake can interface with various visualization packages if they are
installed.  Install one or more of the tools from the following list:
evince, geomview, graphviz, gv, and okular.
