+Contributors must sign the Clojure Contributor Agreement prior to submitting changes.

 The CA is derived from the Oracle Contributor Agreement (OCA), used for OpenJDK, Netbeans and OpenSolaris projects and others. There is a good https://www.oracle.com/technetwork/oca-faq-405384.pdf[OCA FAQ] answering many questions.
 
 By executing the CA, contributors protect the ClojureScript site content and protect the flexibility to adapt the project to the changing demands of the community. In order for the CA to be effective, the ClojureScript project must obtain an assignment for all contributions. Please review the CA for a complete understanding of its terms and conditions. By contributing source code or other material to ClojureScript, you represent that you have a CA with Rich Hickey for such contributions. In order to track contributors, you understand that your full name and username may be posted on a web page listing authorized contributors that is accessible via a public URL.
