- * \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.
- *
