  10     domain, but some restrictions in the MoinMoin COPYING file may apply. Ask a
  11     lawyer.

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