  13     This code has not been tested exhaustively. Use at your own risk.
  14     This code opens the userdict.pickle, and if it gets corrupted, you have a
  15     problem. You have been warned.
  16     The multiple column support has not been tested, but is assumed to be
  17     working.
  18     ***********
  19 
  20     This macro displays a list of currently known users.
  21 
  22     Usage:
  23         [[UserList]]
  24     [[UserList(column1, column2, ...)]]
  25 
  26     Demo. Try pasting the above examples into a MoinMoin sandbox page.
