+Chooses a random element from the non-empty sequence \var{seq} and returns it.

 \begin{funcdesc}{random}{}
 Returns the next random floating point number in the range [0.0 ... 1.0).

 When the module is first imported, the random number is initialized
 using values derived from the current time.

+\begin{funcdesc}{uniform}{a\, b}
+Returns a random real number \var{N} such that \code{\var{a}<=\var{N}<\var{b}}.
+\end{funcdesc}

+When imported, the \code{whrandom} module also creates an instance of
+the \code{whrandom} class, and makes the methods of that instance
+available at the module level.  Therefore one can write either 
+\code{N = whrandom.random()} or:
+\begin{verbatim}
+generator = whrandom.whrandom()
+N = generator.random()
