I think interactive license agreements are annoying. They are all done
deliberately.

Nauty is free as in beer, but the free license it is under is not "libre"
i.e., not OSI approved and not GPL-compatible. Nauty's license is:
"Permission is hereby given for use and/or distribution with the exception
of sale for profit or application with nontrivial military significance."
There are essentially no other restrictions.
Since we have a fundamental disagreement here, this will need to be
discussed on sage-devel and possibly voted on.
