Our copyright policy is modeled after the one of the OpenBSD operating system. We chose one of the most simple and free licenses, the ISC license. It is functionally equivalent to a two-term BSD copyright with language removed that is made unnecessary by the Berne convention.

To ensure that GenomeTools remains absolutely free, we will only accept contributions which have been put under this license.

We use external sources which are covered by their respective licenses. See `LICENSE` file for details.
