Initial License: __________________________________________

Contributor understands and agrees that PSF shall have the irrevocable and perpetual right to make and distribute copies of any Contribution, as well as to create and distribute collective works and derivative works of any Contribution, under the Initial License or under any other open source license approved by a unanimous vote of the PSF board. Contributor shall identify each Contribution by placing the following notice in its source code adjacent to Contributor's valid copyright notice: "Licensed to PSF under a Contributor Agreement."
