 % \section{Usage}
 % This file is designed as a replacement for the \LaTeXe\ standard
 % letter class.  The best way to use it is to get a copy of the
 % file \filenam{blank-ufmathletter.tex}, which will be in the
 % same directory as this file. 
 %  That file is a
 % template which is to be filled out to create a letter.  You will
 % probably want to make your own template file: get
 % a copy of the general template file and fill your personal
 % information and other items which will be the same for all your
 % letters. 
 % 
 % More information on using the \LaTeX\ letter class may be found in
 % most books which cover \LaTeX.  This note discusses a few ways in
 % which the UF mathdepartment letter class file differs from the
 % standard letter class, and gives a few extra hints. 
 % 
 % \paragraph{Personal information.}
 % \DescribeMacro{\date}
 % \DescribeMacro{\name}
 % \DescribeMacro{\location}
 % \DescribeMacro{\telephone}
 % \DescribeMacro{\signature}
 % \DescribeMacro{\UFMtitle}
 % \DescribeMacro{\UFMemail}
 % These macros should  be used in the prefix, before
 % |\begin{document}|, to give the personal information used in the
 % return address and closing.  All are optional except |\name|, and   all
 % are used as follows:
 % \begin{verbatim}
 %    \name{Dr. Joe Doakes}
 %    \signature{Joe Doakes\\President}
 % \end{verbatim}
 % Note that |\\| can be used to break an entry into more than one
 % line.
 % By default, |\signature| will be set to the value of |\name| and
 % |\date| will be the current date.
 % all others will be omitted if not specified.
 %  All of these commands are from the standard \LaTeX\ letter class
 %  except those 
 % starting with |UFM|.
 %
 % \paragraph{Changing line width.}
 % The page parameters |\oddsidemargin| and |\textwidth| may be changed
 % by the user.  For example, the following commands will shrink the
 % line length by 
 % 1 inch.
 % \begin{verbatim}
 % \addtolength{\textwidth}{-1in}
 % \addtolength{\oddsidemargin}{.5in}
 % \end{verbatim}
 % 
 % \paragraph{Avoiding page breaks.}
 % This seems to be better at fitting a letter onto one page than my
 % last attempt at a letterhead style, but sometimes it still needs help.
 %  The following command  will force the whole letter onto one page,
 %  if it is at all reasonable.  It should appear somewhere in
 % the body of the letter.
 % \begin{verbatim}
 % \enlargethispage*{2in} 
 % \end{verbatim}
 % Also, the letter class strongly avoids breaking a
 % paragraph between pages, so it may help to break a paragraph into
 % two. 

 % \paragraph{Miscellaneous.}  
 % \DescribeMacro{nofound}
 % Three new options are
 % provided.   The option \verb|nofound|, used as follows, 
 % will supress printing the slogan "The Foundation of The Gator
 % Nation" at the bottom of the first page.
 % \begin{verbatim}
 %    \documentclass[nofound]{ufmathletter}
 % \end{verbatim}%
 %
 % \DescribeMacro{color}
 % \DescribeMacro{bw}
 %  The option |color| should be used with a color printer.   The
 %  default is black and white, which need not be explicitly specified
 %  by the option |bw|.
 %
 %  The standard print size options, such as |10pt|, |11pt| and |12pt|
 %  may be used as normal.  They will not affect the letterhead.
 %
 % \DescribeMacro{\hoffset}
 % \DescribeMacro{\voffset}
 % Printers vary in the placement of printing on the page.  The
 % commands |\hoffset| and |\voffset| may be used to adjust the output
 % from a particular printer.  They is used as follows:
 % \begin{center}
 %    |\setlength{\hoffset}{| \meta{error} |in}|
 % \end{center}
 % where \meta{error} is the distance (in inches) which the letterhead
 % should be moved to the \emph{right}.  A negative value will move it
 % left.   For vertical movement, a positive argument to |\voffset|
 % will move the printing down.   According to university
 % specifications, the left side of the Logo should be 
 % 2.75 picas (.45 inch) from the left edge and the top of the Logo
 % should be  3.75 picas (.625 inch) from the top edge.
 %
 % \paragraph{The full documentation and code.}
 % In 
 % order to print out full documentation
 % on this file (including a listing of the code) comment out the line
 %  with the command |\OnlyDescription|  (this is about line~33
 % of the file).
 % 
 % Send any bug reports or suggestions to Bill Mitchell,
 % \emph{mitchell@math.ufl.edu}. 
 % \StopEventually{}
 % 
 % \section{The code}
 % This class is derived from the standard \LaTeXe\ letter class,
 % originally following ideas  in Appendix~C of \emph{A Guide to
 % \LaTeXe} by Kopka and Daly.    We begin by declaring the options,
 % then load the |letter| class.
 % \begin{macro}{nofound}
 %   \begin{macro}{color}
 %     \begin{macro}{bw}
 % All three options simply set a flag for later reference.   Note
 % that  the option |bw| actually does nothing, since it is the
 % default.  However that may change.
 %    \begin{macrocode}
 \newif\ifnofoundation             % Don't print foundation line
 \DeclareOption{nofound}{\nofoundationtrue}
 \newif\ifcolor
 \DeclareOption{color}{\colortrue}
 \DeclareOption{bw}{\colorfalse} % Default
 %    \end{macrocode}
 %  \end{macro}
 % \end{macro}
 % \end{macro}
 % \begin{macrocode}
 \DeclareOption*{\PassOptionsToClass{\CurrentOption}{letter}}
 \ProcessOptions
 \LoadClass{letter}
 %    \end{macrocode}

 % \subsection{Personal information}
 % Here we deal with things which are likely to need to be modified.
 % In particular, the part of the letterhead giving the department
 % name and the departmental address is specified here.   The personal
 % data of the actual letter writer is specified in the letter file;
 % howver it is probable that the way such material is presented
 % (which is specified here) could be improved.
 % 
 % \begin{macro}{\fromname}
 % \begin{macro}{\fromlocation}
 % \begin{macro}{\telephonenum}
 % \begin{macro}{\UFM@title}
 % \begin{macro}{\UFM@email}
 % \begin{macro}{\UFMtitle}
 % \begin{macro}{\UFMemail}
 % The commands |\UFM@title| and |\UFM@email| are initially defined to
 % be empty.  User level commands  |\UFMtitle{|\meta{title}|}| and
 % |\UFMemail{|\meta{email address}|}| are provided to set them.
 % The commands |\fromname|, |\fromlocation|, and |telephonenum| are
 % handled similarly by the standard \LaTeX\ letter class.
 %    \begin{macrocode}
 \newcommand*\UFMtitle[1]{\def\UFM@title{#1}}
 \UFMtitle{}
 \newcommand*\UFMemail[1]{\def\UFM@email{#1}}
 \UFMemail{}
 \newcommand*\UFMurl[1]{\def\UFM@url{#1}}
 \UFMurl{}
 %    \end{macrocode}
 % \end{macro}
 % \end{macro}
 % \end{macro}
 % \end{macro}
 % \end{macro}
 % \end{macro}
 % \end{macro}

% \begin{macro}{\UFMunitnames}
% This would be modified for use by a different department.   This was
% written to agree with the illustration in the university
% specifications.   It might be more useful to have the Department be
% the ``primary unit'', and the text of the specifications seems to me
% to suggest this alternative as the department is the unit to which
% replies should be sent.
% \begin{macrocode}
\newcommand{\UFMunitnames}{
     \setlength{\tabcolsep}{0pt}
     \begin{tabular}[t]{l}
       {\blue\PRIMARYUNITFNT College of
         Liberal Arts and Sciences} 
       \\
       {\blue\DEPTNAMEFNT Department of Mathematics}
     \end{tabular}
}
%    \end{macrocode}
% \end{macro}

% \begin{macro}
%   {\UFMreturnaddress}
%   This would also have to be modified (in the obvious way) for use by
%   a differerent department.

%   The text here will 
%   stick out the bottom of the heading, but does not 
%   change \TeX{}'s notion of the size of the box containing the head.
%   Thus there is no explicit provision to
%   ensure that this material doesn't overlap the actual letter.
%   \begin{macrocode}
\newcommand{\UFMreturnaddress}{
  \setlength{\tabcolsep}{0pt}
  {
      \def\arraystretch{.85}%
      \DEPTADDRFNT\blue
      \begin{tabular}[t]{l}

      \end{tabular}%
    }
}
%    \end{macrocode}
% \end{macro}


% \begin{macro}
%   {UFMpersonaladdress}
%   Modifications to the presentation of personal information would be
%   made here.   Note that the actual information is specified in the
%   file with the letter.    Any of these items can be omitted simply
%   by not defining them there, so a modification would only be needed
%   if it is desired to present this information elsewhere in the
%   letter or differently here.
%   \begin{macrocode}
\newtoks\UFMpersonaladdress

%\subsection{Printing the first page}
%
% \begin{macro}{\opening}

% change this except to correct errors.

% later.   It is defined here, inside |\opening| is running, so
% that personal information from the letter file can be incorporated.  
% The footer will be defined later, outside of the macro |\opening|,
