+ * \brief Test function for randpool API.
+ *
+ * This program return a rand number generate from randpool function.
+ * For use randpool function you need a souce of entropy. In this
+ * program you can choose from:
+ * - /dev/random
+ * - /dev/urandom
+ * - /dev/input/mouse0
+ *
+ * There are 3 mode of output:
+ * - binmode: program generate a sequenze of random byte.
+ * - Matrix of random number for octave program.
+ * - Vector of random number for octave program.
