To take an existing project and turn it into a clojure-contrib project:

All past contributors on the project must:

• Have submitted a Clojure Contributor Agreement (CA)
• Send an email to the clojure-dev mailing list granting permission

The email should say:

"I, (YOUR NAME), give my permission to release my contributions to (PROJECT) under the Clojure Contributor Agreement."

Once a project is in contrib:

• Patches may only be accepted from signers of the CA
• All contributions are automatically governed by the terms of the CA
