Got it, OK let me clarify that for you then. Yes. That is what makes
it GPL-Compatible. We droped the Dual GPL/BSD practice and picked up
the ISC license to help OpenBSD when we took Reyk's HAL from OpenBSD.
The ISC license is just a simpler BSD license due the Berne Convention
which makes one of the clauses implicit (respecting copyright between
countries). Its just a very simple permissive license.
