+%%%%%%
+% 
+% Some of the following contributions came years ago, others quite
+% recently:
+%
+% Spanish: Juanjo <jj.hfmc@gmail.com> and Lee Rudolph <lrudolph@panix.com>
+%
+% Corrections of Italian orthography: Paolo Cusinu <paolo.cusinu@gmail.com>
+% 
+% Estonian and a patch for using fp: Priit Laes <plaes@plaes.org>
+%
+% Another patch for fp: AFresh1, March 2011 % e-mail: andrew@afresh1.com
+%
+% One variant of Spanish: Matias Banchoff <matiasb@cespi.unlp.edu.ar>
+%
+%%%%%%
+% Jacopo, May 2003
+% e-mail: jacopo@
+%
+%   Contributed labels in Italian.
+%
+%%%%%%
+% O. Corff, July 2003 
+% 
+%   fixed one nasty spacing bug, simplified internal table 
+%   construction (table now has five instead of six columns,
+%   the second of which was never used).
+%
+%%%%%%
+% Johann Spies, January 21, 2002
+% e-mail: jspies@sun.ac.za
+%
+%   Hinted that \Subtotal Project should show the project name
+%   rather than just `Project'.
+%
+%   Contributed labels in Afrikaans.
+%
+%%%%%%
+% Robin Fairbairns, December 6, 2001
+% 
+%   Hinted that the dollar sign can also be printed by saying
+%   \string$.
+%
+%%%%%%
+% Vincent Tougait, France, November 27, 2001
+%
+%   Pointed out that fractions of VAT percents were not allowed.
+%   Bugfix on December 06, 2001
+%
+%%%%%%
+% Fred Donck, The Hague, The Netherlands, October, 2001
+% e-mail: fd0@donck.com
+%
+% Dutch labels
+%
+%%%%%%
+% Ian Wormsbecker, October 31, 2001
+%
+%   Skips the VAT lines if VAT=0
+%   Noticed that the terminal message will not accept a Dollar sign.
+%   The only workaround is to say \char`$ in \begin{invoice}{}
+%
+%%%%%%
+% Fred Donck, The Hague, The Netherlands, Sept 18, 2001
+% e-mail: fd0@donck.com
+%
+% fixed some minor issues:
+%   real arithmetic will use integer intermediate values, so
+%   some calculations failed with the \Fee{title}{rate}{amount}
+%   where \rate is not an integer
+%
+%   another fix is that in my opinion the VAT line should be 
+%   printed also even though only one project is specified
+%
+%   third fix is that the subtotal-line should not be printed 
+%   on a project with only one \Fee line
+%
+%%%%%%
+% Jacco Kok (fixed some labels),
+%
+%%%%%%
+% Thilo Barth (discussed alternative names and command clashes
+%	with KOMA Script class scrlettr.cls),
+%
+%%%%%%
+% Robert Inder (discussed general issues)
+%
+% were gladly and gratefully received and accepted.
