 > Any idea what "It applies to all of the nauty files, but for
 incorporation into Sage you can ignore it" actually means? The problem is
 that it really needs to be GPL v3 to be standard in Sage. And once it's
 GPL, it's GPL for everybody, not just for Sage.

 And even restriction to non-military applications is a problem. Who can be
 ''sure'' that there will never be any military application for posets?

 Do we have someone who is better to discuss with McKay about these license
 issues?
