DESCRIPTION

12              Read graphs or digraphs and colour their vertices in in all pos‐
13              sible ways with colours 0,1,2,... .  Isomorphic  graphs  derived
14              from  the  same  input  are suppressed.  If the input graphs are
15              non-isomorphic then the output graphs are also.
16
17       -e# | -e#:#
18              specify a value or range of the total value of the colours
19
20       -m# number of available colours (default 2)
21
22       -f# Use the group that fixes the first # vertices setwise
23
24       -T     use a simple text output format (nv ne {col} {v1 v2})
25
26       -u     no output, just count them
27
28       -q     suppress auxiliary information
