%description
Software package for the Random number generation & testing.
A suite of statistical tests for fast PRNGs. Multithreaded for speed,
command-line tools for automation, no upper limit on data size.
A variety of C++ pseudo-random number generators with well-designed
interfaces aimed at practical uses, not just research.

Features:
  * A convenient & powerful interface to RNG algorithms
  * A variety of fast high quality RNG algorithms
  * Fast & effective statistical tests for RNGs
