+     "This module can test routines that manipulate random numbers by
+providing a known output from @code{rand}.  Given a list of seeds with
+@code{srand}, it will return each in turn.  After seeded random numbers are
+exhausted, it will always return 0.  Seed numbers must be of a form that
+meets the expected output from @code{rand} as called with no arguments: they
+must be between 0 (inclusive) and 1 (exclusive).  In order to facilitate
+generating and testing a nearly-one number, this module exports the function
+@code{oneish}, which returns a number just fractionally less than one.")
