DESCRIPTION

12              Add a specified number of new vertices
13
14              The output file has a header if and only if the input file does.
15
16       -l     canonically label outputs
17
18       -c     join each new vertex to all the old vertices
19
20       -k     make a clique on the set of new vertices
21
22       -n# the number of new vertices (default 1)
23
24       -j# join a new vertex to # old vertices in all possible ways
25
26              (-j is incompatible with -n)
27
28       -i     for a digraph, edges go towards the old vertices
29
30       -o     for a digraph, edges go away from the old vertices
31
32              (-i is the default if neither -i nor -o is given)
33
34       -q     Suppress auxiliary information
