+      The haveged project is an attempt to provide an easy-to-use, unpredictable
+      random number generator based upon an adaptation of the HAVEGE algorithm.
+      Haveged was created to remedy low-entropy conditions in the Linux random device
+      that can occur under some workloads, especially on headless servers. Current development
+      of haveged is directed towards improving overall reliablity and adaptability while minimizing
+      the barriers to using haveged for other tasks.
