+
+While Common Lisp does provide a @code{RANDOM} function, it does not allow the
+user to pass an explicit @code{SEED}, nor to portably exchange the random
+state between implementations.  This can be a headache in cases like games,
+where a controlled seeding process can be very useful.
+
+For both curiosity and convenience, this library offers multiple algorithms to
+generate random numbers, as well as a bunch of generally useful methods to
+produce desired ranges.")
