         For any project, it's critical to know how the software is used, but tracking usage data is inherently difficult in open-source projects.
         Anonymous usage statistics address this need.
         When enabled, Jenkins periodically sends information to the Jenkins project.
         The Jenkins project uses this information to set development priorities.
