+the generation and use of entropy.  The Data::Entropy::Source class
+manages the entropy coming from a particular source.  This class acts
+as a layer over a raw entropy source, which may be a normal I/O handle
+or a special-purpose class.  The Data::Entropy::RawSource::* classes
+provide fundamental sources of entropy.  The sources specially
+supported are an OS-supplied entropy collector, downloads from servers
+on the Internet, and cryptographic fake entropy.  The
+Data::Entropy::Algorithms module contains a collection of fundamental
+algorithms that use entropy.  There are random number generators and
+functions to shuffle arrays.")
