Teapot is copyright (c) by Michael Haardt, 1995, 1996, 1997, 2001.  

The implementation of clocked expressions is modelled after the
description of clocked evaluation in the PhD work of J�rg Wittenberger
<joerg.wittenberger@inf.tu-dresden.de> at the University of Technology
in Dresden, Germany.  The German message catalog was contributed by
Guido M�sch, the Dutch catalog by Wim van Dorst
<baron@clifton.hobby.nl> and the Ukrainian catalog by Volodymyr
M. Lisivka <lvm@mystery.lviv.net>.  The trigonometric functions were
inspired by Koniorczyk M�ty�s <kmatyas@cs.elte.hu>.  The context
output format was contributed by Marko Schuetz <MarkoSchuetz@web.de>.
