DESCRIPTION

              The output file has a header if and only if the input file does.  Undirected graphs
              are passed through without change, while directed graphs are  written  in  digraph6
              format.

       -a     Also output the original graph (before the converse)

       -c     Output only self-converse digraphs

       -q     Suppress auxiliary information.
