%                    Numerical date function: \todaynum
% *1990-12-03 Changed: The Draft header changed to 
%                     "Revised: date    Draft     Typset: date, time"
%             Added: \timehhmm \hour \minute \countertoxx
% *1990-12-06 Changed: Page format parameters changed to center text on page
% *1991-01-06 Changed: The word ``Draft'' in the draft-header is
%                      replaced by the file-name (\jobname)
% *1991-01-14 Changed: New fonts and sizes in the draft header
% *1991-01-29 Added: \tag for draft header
% *1991-02-22 Added: Reduction of vertical white space:
%                    * Around displays:
%                       The size of \above(below)displayskip is reduced,
%                       almost all of the rubbespace is removed.
%                    * Around headings:
%                       + The font size in the headings are reduced.
%                       + The amount of white space before and after
%                         the heading are reduced, no rubber-space.
%             Added: New optional parameter to the proof environment,
%                    \begin{proof}[Lemma 2.3] produces the text
%                    ``Proof of Lemma 2.3: '' at the begining of the proof.
%             Changed: The proof environment is rewritten:
%                      * We are now using a \trivlist, this makes the proof
%                        environment behave just like the theorem type 
%                        environments.
%                      * The end-of-proof Box will appear at the end of 
%                        the current line if at least 1/9 of the line is 
%                        empty. Otherwise its palced at the end of the 
%                        next line.
% *1991-02-24 Added: \eref \lref \tref \pref \cref,
%                    Shorthands for referencing equations, lemmas,
%                    theorems, propositions, and corollaries.
% *1991-03-05 Added: remark environment; example environment
%             Fixed: oparg in theoremlike environments
% *1991-03-21 Added: \widowpenalty
% *1991-03-27 Added: New environment for acknowledgements
% *1991-04-19 Added: New command \inputfilename, used as default value
%                    for \mark in the draft-mode.
% *1991-05-31 Fixed: \timehhmm worked incorrectly combined with \include,
%                    since include restored old values to the counters.
%                    Simple solution: use \edef instead of \def when defining
%                    \timehhmm.
% *1991-06-17 Added: \lefteqtext => Text starting at left margin inside
%                    an eqnarray type environment.

% *1991-08-08 Chang: Draft part put into separate file.
