Integrate good code from any source with acceptable
licenses.
ISC or Berkeley style licences are preferred, the GPL is not acceptable
when adding new code, NDAs are never acceptable.
We want to make available source code that anyone can use for ANY
PURPOSE, with no restrictions.
We strive to make our software robust and secure, and encourage
companies to use whichever pieces they want to. There are
commercial spin-offs of OpenBSD.
