+    Copyright (c) 2007-2013 Contributors as noted in the AUTHORS file
+
+    This file is part of 0MQ.
+
+    This tool generates a CurveZMQ keypair, as two printable strings you can 
+    use in configuration files or source code. The encoding uses Z85, which 
+    is a base-85 format that is described in 0MQ RFC 32, and which has an 
+    implementation in the z85_codec.h source used by this tool. The keypair 
+    always works with the secret key held by one party and the public key 
+    distributed (securely!) to peers wishing to connect to it.
+
+    0MQ is free software; you can redistribute it and/or modify it under
