 synopsis:            High-quality splittable pseudorandom number generator
 
 -- A longer description of the package.
-description:         This package contains an implementation of a high-quality splittable pseudorandom number generator. The generator is based on a cryptographic hash function built on top of the ThreeFish block cipher. See the paper /Splittable Pseudorandom Number Generators Using Cryptographic Hashing/ by Claessen, Pałka for details and the rationale of the design.
