   3 \stmodindex{rand} This module implements a pseudo-random number
   4 generator with an interface similar to \code{rand()} in C\@.  It defines
   5 the following functions:
   6
   7 \renewcommand{\indexsubitem}{(in module rand)}
   8 \begin{funcdesc}{rand}{}
   9 Returns an integer random number in the range [0 ... 32768).
  10 \end{funcdesc}
  11
  12 \begin{funcdesc}{choice}{s}
  13 Returns a random element from the sequence (string, tuple or list)
  14 \var{s}.
  15 \end{funcdesc}
  16
  17 \begin{funcdesc}{srand}{seed}
  18 Initializes the random number generator with the given integral seed.
  19 When the module is first imported, the random number is initialized with
  20 the current time.
  21 \end{funcdesc}
