addptg [-lq] [-n#] [-j#] [-ck] [-io] [infile [outfile]]

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# join a new vertex to # old vertices in all possible ways

(-j is incompatible with -n)

	-i

	-o		for a digraph, edges go away from the old vertices

(-i is the default if neither -i nor -o is given)
