Modifications to the unix kernel (terminal linking/advising)

[Ron Natalie]

You can't sell what you wrote on an educational license.  You can charge
for your time installing it on someone elses system.  We go by the same
guidelines for government programs.  They belong to the government, we
give them out for nothing.  You want help on using or installing it?  Well
that's people time and that costs.

I guess I shouldn't deflate your balloon by telling you that LLL already
implemented the link-up feature and gives it away.
