[erlang-questions] Is there an accepted way of including GPL code in a project?

Thanks for the summary, I think it sums up my feelings on this as well.
I already sent the author an email before posting this question.
Ideally I'd like to use his code with his permission either as you say
under a different license agreement or an acknowledgement that what
I'm proposing is acceptable to him.
I think I'll send him another email before I decide on the path I'm
going to take.
