pz.org is a project that reflects research into programming tools that are outside the mainstream. The main work is done by Andrew Binstock and various colleagues, as well as unknown contributors. Almost all the code here can be used under an open-source license or dual-licensing scheme. So feel free to explore, download, use, and send us feedback. The feedback address is (remove all hyphens and make the necessary changes) feed-ba-ck(at) pz (dot) org
