If defined, the digraph version is shown in parentheses;
# size parameter called n in the descriptions.
.TP
\fB\-p\fR#
: path (directed path) on n vertices.
.TP
\fB\-c\fR#
: cycle (directed cycle) on n vertices.
.TP
\fB\-e\fR#
: empty graph (digraph with loops only) on n vertices.
.TP
\fB\-k\fR#
: complete graph (with loops) on n vertices
.HP
\fB\-b\fR#,#[,#] : complete bipartite graph (directed l\->r) on n vertices
.IP
minus a matching of given size if present
