%description
The Mersenne Twister is an exceptionally high-quality, fast random number
generator.  This package contains two versions of it in Java, written by Sean
Luke.  MersenneTwister is a complete drop-in subclass replacement for
java.util.Random.  MersenneTwisterFast is algorithmically identical, except
that it isn't synchronized, and it's not a subclass of Random.  This, plus
other speed improvements, makes it over twice the speed.
