 // RLZ is a library which is used to measure distribution scenarios.
 // Its job is to record certain lifetime events in the registry and to send
 // them encoded as a compact string at most twice. The sent data does
 // not contain information that can be used to identify a user or to infer
 // browsing habits. The API in this file is a wrapper around the open source
 // RLZ library which can be found at http://code.google.com/p/rlz.
 //
 // For partner or bundled installs, the RLZ might send more information
 // according to the terms disclosed in the EULA.
