 # uuid ![build status](https://travis-ci.org/pborman/uuid.svg?branch=master)
 The uuid package generates and inspects UUIDs based on [RFC 4122](http://tools.ietf.org/html/rfc4122) and DCE 1.1: Authentication and Security Services. 
 
+This package now leverages the github.com/google/uuid package (which is based off an earlier version of this package).
