Contributor License Agreement (CLA)

CLA’s are increasingly used by many open source projects. A CLA ensures that potential contributors and PKP establish a basic but binding agreement for all code contributions. The PKP CLA is based on the one used by the Apache Software Foundation. It was reviewed by one of PKP’s major development partners before it was adopted by PKP.
