%description
Nauty and Traces are programs for computing automorphism groups of
graphs and digraphs.  (At present, Traces does not accept digraphs.)
They can also produce a canonical label.  They are written in a portable
subset of C, and run on a considerable number of different systems.

There is a small suite of programs called gtools included in the
package.  For example, geng can generate non-isomorphic graphs very
quickly.  There are also generators for bipartite graphs, digraphs, and
multigraphs, and programs for manipulating files of graphs in a compact
format.

%description -n libnauty
Nauty (No AUTomorphisms, Yes?) is a set of procedures for computing
automorphism groups of graphs and digraphs.  This package contains a
library of nauty procedures.
