+/**
+ * @addtogroup rng_module Random number generator (RNG) module
+ *
+ * The Random number generator (RNG) module provides random number
+ * generation, see \c havege_rand(). It uses the HAVEGE (HArdware Volatile
+ * Entropy Gathering and Expansion) software heuristic which is claimed
+ * to be an unpredictable or empirically strong* random number generation.
+ *
+ * \* Meaning that there seems to be no practical algorithm that can guess
+ * the next bit with a probability larger than 1/2 in an output sequence.
+ *
+ * This module can be used to generate random numbers.
