% \begin{abstract}
% This package is intended to print a term calendar for use in
% planning a class.  It has a flexible mechanism for
% specifying which days of the week are to be included and for inserting text
% either regularly on the same day each week, or on selected days,  
% or for a series of consecutive
% days.  It also has a flexible mechinism for specifing class and
% nonclass days.  Text may be inserted into consecutive days so that
% it 
% automatically flows around nonclass days.
% \end{abstract}
% \section{Description}  The main command in this package is the
% |calendar| environment\DescribeEnv{calendar}.  Figure~1 shows an 
% example of its use, which might be suitable for a
% Monday-Wednesday-Friday class with a Thursday recitation in a
% mercifully short term.  The \LaTeX\ input to generate it is given
% in figure~2.

% 
% The two arguments to the |calendar| environment are the starting date,
% in the format |m/d/y|, and the number of weeks to be printed.  The
% contents of the environment describe what is to appear in the
% calendar.  The commands fall into two classes: those which specify
% what is to be printed on a particular day in each week, and those
% which specify what is to be printed on specific days during the term.
% 
% The commands which specify what each week is to look like are
% |\calday| and
% |\skipday|.
% These commands specify the days of the week in order; thus there
% should be seven of them (athough ten may be prefered for a course
% covering the French 
% revolution).
% The macro |\skipday|\DescribeMacro{\skipday}\
%  simply declares that the corresponding day should
% not be printed in the exam; thus the sample calendar has boxes only
% for Monday, Wednesday, Thursday, and Friday.  The macro
% |\calday[|\inp{optional~head}|]{|\inp{option~list}|}|
% \DescribeMacro{\calday}
% is used to specify a day which is to be printed.  The required
% argument \inp{option~list}
% is a (possibly empty) list of \TeX\ commands which are executed
% before the text for that day is printed.
% It can (at least in principal) include 
% any \LaTeX\ command, but several commands, described below, are
% provided  specifically for this purpose.  The optional argument
% is the text of a heading for that day 
% which will at the top
% of each page of the calendar.

% \paragraph{Available options.}
% The macros |\classday| 
% \DescribeMacro{\classday}\DescribeMacro{\noclassday}
% and |\noclassday| declare that the specified day is, or is not, a
% class day.  Days specified as class days are numbered and can be
% refered to by their numbers.
% The command |\weeklytext{|\inp{text}|}| specifies that the
% \DescribeMacro{\weeklytext}
% indicated text should appear every week in the box for that day.
% The \inp{text}
% may include \TeX\ commands;  for example the following could be used
% to number regular Monday quizes:
% \begin{verbatim}
% \weeklytext{\stepcounter{quiznumber} Quiz~\arabic{quiznumber}}
% \end{verbatim}
%
% \paragraph{Options for a specific day}  are specified by the command 
% |\options{|\inp{day}|}{|\inp{option list}|}|.
% \DescribeMacro{\options}
% The \inp{option~list} argument is exactly the same as for |\calday|.  The
% options added by |\options| are executed after those for |\calday|,
% and thus may be used to modify or nullify for a specific day the
% general instructions specified for a particular day of the  week.
%  If there  no quiz is planned for  Halloween then  
% |\options{10/31/94}{\weeklytext{}}| could be used to supress
% printing the usual weekly message.
% 
% There are two ways of specifing the \inp{day} argument of
% |\options|.  First, the date may be specified, in the format
% \texttt{m/d/y}; for example 
% \begin{verbatim}\options{11/11/94}{\noclass}\end{verbatim}
% specifies, that November 11th, Veterans's day, is not a class day. 
% The second method of specifying the date is by its number: 
% \begin{verbatim}\options{C6}{\weeklytext{}}\end{verbatim}
%  would supress the normal text on the
% sixth day of class.  Of course, only days specified as class days
% can be addressed in this style.
% 
% \paragraph{Inserting Text.} There is a similar provision for text to
% be printed on a specific day, 
% using the command |\caltext|. \DescribeMacro{\caltext}  The command 
% \begin{verbatim}\caltext{10/31/94}{Halloween\\No Quiz!} \end{verbatim}
%  will print the indicated
% message on October 31, and 
%  |\caltext{C6}{Hour Exam}|
% ^^A \begin{verbatim}\caltext{C6}{Hour Exam}\end{verbatim} 
%  will  
% print the indicated message on the sixth class day.
% 
% Two extra commands are provided to simplify the job of entering text for
% consecutive class days, as in specifying the lecture topic or
% homework for each day.  The command 
% \DescribeMacro{\caltexton}\DescribeMacro{\caltextnext}
% |\caltexton{|\inp{class day}|}{|\inp{text}|}| specifies a
% starting day and inserts the
% indicated text on that day.  The command
% |\caltextnext{|\inp{text}|}| can  then be used to print text on 
% successive class days.  The command |\caltextnext{}|, with an empty
% argument, may be used to skip days.
% 
% \subsection{Modifying the style of the calendar}
% Several parameters and commands will allow some modfication of the
% style of the entire calendar.  The size of the calendar is specified
% by |\calboxdepth|\DescribeMacro{\calboxdepth}, which specifies the
% minimum height of the box for each day, and
% |\calwidth|\DescribeMacro{\calwidth}\ which specifies the width of the
% calendar. The defaults are 1~inch for |\calboxdepth| and |\textwidth|
% for |\calboxwidth|. 

% The printing of the date and classnumber in each box is done by the
% commands |\calprintdate| and |\calprintclass|.  The default
% definitions of these macros are as follows:
% \begin{macro}{\calprintdate}
%    \begin{macrocode}
\newcommand{\calprintdate}{%
    \ifnewmonth\framebox{\monthname\ \ordinaldate}%
    \else \ordinaldate\fi
  }
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\calprintclass}
%    \begin{macrocode}
\newcommand{\calprintclass}{\textbf{\small\theclassnum}}
%    \end{macrocode}
% \end{macro}
% They may be changed with |\renewcommand|.
%
% By default the calendar will automatically be split over several
% pages.  This can be avoided by putting the entire calendar in a
% |\vbox|. It will normally also be necessary to change |\calboxdepth|
% so that the calendar will fit on one page.

% |\calday|, and prints a typical week.  It will be filled up by the macros
% |\calday| and |\skipday|.
%    \begin{macrocode}

%    \end{macrocode}
% \end{macro}
% After a couple of preliminaries, we will define the command
% |\ca@doaday| which is
% actually prints out
% the text for each day of the calendar.
% \begin{macro}{c@classnum} This is the counter used to keep track of
% class days.  It is initialized to 1 in the beginning of the
% |calendar| environment.
%    \begin{macrocode}
\newcounter{classnum}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\ca@normbs} 
% The meaning of |\\| is changed by the |longtable| environment.
% We save its standard meaning so that it can be used 
% in the text to be printed in the calendar boxes.
%    \begin{macrocode}
\let\ca@normbs=\\
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\ca@doaday} 
% The command |\ca@doaday| does the actual printing of the contents of
% the box for each day.
% First the options are read, in the following order:
% options specified in the argument to |\calday|, then options
% specified by date, and finally 
% options specified by  classday.  
%    \begin{macrocode} 
\newcommand\ca@doaday[1]{
   \hbox{\vrule depth \calboxdepth height 0pt width 0pt\vtop{

   \hbox to \hsize{\calprintdate\hfill\ifclassday\calprintclass\fi}
   \vspace{2pt}
%    \end{macrocode} 
% Now we are ready to print the text.   We do it inside a group in which

%    \end{macrocode}
% \end{macro}
% \subsection{Options}
% The options and text for the individual days are stored in macros,
% with names of the form |\|\inp{date}|options| or
% |\|\inp{date}|text|. 
%
% \begin{macro}{\ca@addmacro} |\ca@addmacro| is like |\ca@addtoks|,
% except it works on macros instead of token boxes.  The first
% argument is the name of a 
% macro (without the backslash) and the second is a sequence of
% tokens to be added to its definition.  The definition is taken from
% the 
% \TeX{}book, exercise 20.15.  Note that the spaces in the last line
% are essential. 
%    \begin{macrocode}
\long\def\ca@addmacro#1#2{
 \expandafter\ifx\csname#1\endcsname\relax%
        \expandafter\def\csname#1\endcsname{#2}
  \else
  \toks0=
     \expandafter\expandafter\expandafter{\csname#1\endcsname}
  \toks2={#2}
  \expandafter
    \edef\csname#1\endcsname{\the\toks0 \the\toks2 }\fi}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\options} |\options#1#2| adds the tokens in the second
% argument to the macro with the name |\csname #1options\endcsname|.
%    \begin{macrocode}
\newcommand\options[1]{\ca@addmacro{#1options}}
%    \end{macrocode}
% \end{macro}
% Now the code for the varions options.
%
% \begin{macro}{\ifclassday}
% \begin{macro}{\classday}\begin{macro}{\noclassday}  
% A switch determines which days are class days.
%    \begin{macrocode}
\newif\ifclassday
\newcommand{\classday}{\classdaytrue}
\newcommand{\noclassday}{\classdayfalse}
%    \end{macrocode}
% \end{macro}\end{macro}\end{macro}
%
% \begin{macro}{\weeklytext} This token box holds the standard text
% for each day of the week.  It is filled and immediately used by
% |\ca@doaday|,
% inside the hbox containing each calendar day.
%    \begin{macrocode}
\newtoks\weeklytext
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\caltext}
% This macro works like |\options| to save the
% text for a specific day, saving the text in a macro  with the name
% |\csname #1text\endcsname|.  We add |\par| after the text, so
% successive texts for the same day start on separate lines.  We use
% |\par| instead of |\\| since it is harmless if it is unneeded (but
% requires that |\ca@addmacro| be long).
%    \begin{macrocode}
\newcommand\caltext[2]{\ca@addmacro{#1text}{#2\par}}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\c@textdaycount}\begin{macro}{\caltexton}
% \begin{macro}{\caltextnext}
% The commands |\caltexton| and |\caltextnext| use |\caltext| with the
% day determined by the counter |textdaycount|.
%    \begin{macrocode}
\newcounter{textdaycount}\setcounter{textdaycount}1
\newcommand\caltexton[2]{\setcounter{textdaycount}{#1}
        \caltext{C#1}{#2}}
\newcommand\caltextnext[1]{\advance\c@textdaycount by 1
        \caltext{C\thetextdaycount}{#1}}
%    \end{macrocode}
% \end{macro}\end{macro}\end{macro}
% \subsection{Macros concerned with date calculations}
% Now we have a selection of macros which are concerned with
% calculating the dates in the calendar.
% \begin{macro}{\c@date} Counter for the day of the month.
%    \begin{macrocode}
   \newcounter{date}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\c@month} Counter for  month (January = 1)
%    \begin{macrocode}
   \newcounter{month}

% \end{macro}
% \begin{macro}{\c@year} Counter for year.
%    \begin{macrocode}
   \newcounter{year}

% \end{macro}
% \begin{macro}{\curdate}Print out the date.
%    \begin{macrocode}
\newcommand\curdate{\arabic{month}/\arabic{date}/\arabic{year}}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\monthname} Print the name of the Month.
%    \begin{macrocode}
\newcommand\monthname{\ifcase\c@month\or Jan\or Feb\or Mar\or Apr%

% \begin{macro}{\advancedate} Move the  date forward by one day.
%    \begin{macrocode}
\newcommand\advancedate{\stepcounter{date}
    \ifnum\thedate&gt;\monthlength\relax
       \addtocounter{date}{-\monthlength}\advancemonth\fi}
