+fast pseudo-random number generator.  It is suitable for applications where a
+significant amount of random data needs to be produced quickly, such as
+solving using the Monte Carlo method or for games.  The results are uniformly
+distributed, unbiased, and unpredictable unless you know the seed.
+
+This package provides a Perl interface to the ISAAC pseudo random number
+generator.")
