+     "haveged generates an unpredictable stream of random numbers for use by
+Linux's @file{/dev/random} and @file{/dev/urandom} devices.  The kernel's
+standard mechanisms for filling the entropy pool may not be sufficient for
+systems with high needs or limited user interaction, such as headless servers.
+@command{haveged} runs as a privileged daemon, harvesting randomness from the
+indirect effects of hardware events on hidden processor state using the HArdware
+Volatile Entropy Gathering and Expansion (HAVEGE) algorithm.  It tunes itself to
+its environment and provides the same built-in test suite for the output stream
+as used on certified hardware security devices.")
