Add a specified number of new vertices The output file has a header if and only if the input file does. -l canonically label outputs -c join each new vertex to all the old vertices -k make a clique on the set of new vertices -n# the number of new vertices (default 1) -j# -j#:# join a new vertex to # old vertices in all possible ways -e# -e#:# use all joins that give the new graphs # edges (-j, -e are each incompatible with -n) -i for a digraph, edges go towards the old vertices -o for a digraph, edges go away from the old vertices (-i is the default if neither -i nor -o is given) -q Suppress auxiliary information
