  following method, specific to the Wichmann-Hill algorithm:
  
! \begin{funcdesc}{seed}{x, y, z}
    Initializes the random number generator from the integers \var{x},
    \var{y} and \var{z}.  When the module is first imported, the random
    number is initialized using values derived from the current time.

  following method, specific to the Wichmann-Hill algorithm:
  
! \begin{methoddesc}[whrandom]{seed}{\optional{x, y, z}}
    Initializes the random number generator from the integers \var{x},
    \var{y} and \var{z}.  When the module is first imported, the random
    number is initialized using values derived from the current time.
!   If \var{x}, \var{y}, and \var{z} are either omitted or \code{0}, the 
!   seed will be computed from the current system time.  If one or two
!   of the parameters are \code{0}, but not all three, the zero values
!   are replaced by ones.  This causes some appearantly different seeds
!   to be equal, with the corresponding result on the pseudo-random
!   series produced by the generator.
