these documentation files, so they can use it, too.
New Features
============
Version 1.1 of the Random class adds the following features from Version 1.0:
* Gaussian variables;
* Arbitrary distribution (via randFunc: method);
* Nicer distribution policy;
* Two neat histogram testing programs, one for flat distributions
(from percent method), and one for Gaussian distributions (from
gaussian method).
