[Nauty] dreadnaut from commandline

[Sterten at aol.com]

I want to run dreadnaut from commandline and from DOS-batchfile.
[BTW.why is it called dreadnaut ? , dread = fear according to my dic.]


e.g. I want to print the sizes of the automorphismgroups
of all graphs (digraphs,relations) of order 5.

I start with

geng 5 graph5

to generate the graphs and store them in file "geng5"
Then I'd like to run something like:

dreadnaut -size graph5 sizes5
or autosize graph5 sizes5

There is probably a way to make a program which does this
by calling nauty with the appropriate parameters.
Has someone already done it ?
