+% The standard "\makelabels" command in the \LaTeXe\ "letter.cls"

+% may want more. \EL\ redefines "\makelabels" in\footnote{hopefully}
+% a more useful and customizable way
+%
+% The detailed usage of the package is described in the file

+% There are three kinds of things we can print: envelopes (default)

+%
+% \DescribeMacro{\if@rotateenvelopes}

+% Now we must determine whether we want to rotate envelopes and

+% \begin{macrocode}
+\newif\if@rotateenvelopes
+\@rotateenvelopestrue
+\newif\if@printreturnaddress
+\@printreturnaddresstrue
+% \end{macrocode}
+%
+% \DescribeMacro{\@envelopeposition}
+% Now let us decide how to print envelopes. They can be either centered
+% (default) \emph{or} shifted to the left or to the right of the paper
+% tray. The
+% counter "\@envelopeposition" can be, correspondingly, either 0 or 1
+% or 2. The value of
+% 3 corresponds to the ``custom placing'', when the user sets
+% "\EnvelopeLeftMargin" manually.
+%
+% \begin{macrocode}

+% The switches "\if@pswait" and "\if@psautotray" control optional manual

+% (see Section~\ref{sec:Print} for details). The register
+% "\PSEnvelopeTray" contains the name of the required tray.

+%
+% \begin{macro}{\if@barcodes}
+% \begin{macro}{\if@alwaysbarcodes}
+% We can either print bar codes (default) or not. The second switch

+%
+% \subsection{Lengths and numbers}
+%
+% We want all lengths to be user settable, so no "@" in the names.
+%
+%
+% \DescribeMacro{\EnvelopeWidth}
+% \DescribeMacro{\EnvelopeHeight}
+% \DescribeMacro{\EnvelopeTopMargin}
+% \DescribeMacro{\EnvelopeLeftMargin}
+% An envelope has four basic lengths.
+% The first two are self-evident. The third is the distance between the
+% edge of the paper and the leading edge of the envelope. All
+% pre-defined envelope sizes set this to zero. The fourth is the distance
+% between the left edge of the paper and the envelope. Its value depends
+% on the value of the "\@envelopeposition" variable. We will preset it to
+% zero
+% \begin{macrocode}
+\newlength{\EnvelopeWidth}
+\newlength{\EnvelopeHeight}
+\newlength{\EnvelopeTopMargin}
+\newlength{\EnvelopeLeftMargin}
+\setlength{\EnvelopeLeftMargin}{0pt}
+% \end{macrocode}
+%
+%
+% \DescribeMacro{\LabelWidth}
+% \DescribeMacro{\LabelHeight}
+% \DescribeMacro{\LabelTopMargin}
+% \DescribeMacro{\LabelLeftMargin}
+% \DescribeMacro{\LabelRightMargin}
+% A label has more parameters.
+% The first two are the same as for the envelopes. The next two define the
+% distances from the paper edges to the beginning of the labels. The
+% last one describes the distance between the labels.
+% \begin{macrocode}
+\newlength{\LabelWidth}
+\newlength{\LabelHeight}
+\newlength{\LabelTopMargin}
+\newlength{\LabelLeftMargin}
+\newlength{\LabelRightMargin}
+% \end{macrocode}
+%
+% \DescribeMacro{\c@LabelMaxCol}
+% \DescribeMacro{\c@LabelMaxRow}
+% The following numbers define, how many labels are in each row and how
+% many rows are on each page
+% \begin{macrocode}
+\newcounter{LabelMaxCol}
+\newcounter{LabelMaxRow}
+% \end{macrocode}
+%
+% The lengths above are \emph{external} parameters that determine an
+% envelope or a label. Now we will describe \emph{internal} lengths. We
+% define them here because the commands "\SetEnvelope" and "\SetLabel"
+% determine them basing on the given envelope or label type.
+%
+%
+% \DescribeMacro{\FromAddressTopMargin}
+% \DescribeMacro{\FromAddressLeftMargin}
+% \DescribeMacro{\FromAddressHeight}
+% \DescribeMacro{\FromAddressWidth}
+% \DescribeMacro{\ToAddressTopMargin}
+% \DescribeMacro{\ToAddressLeftMargin}
+% \DescribeMacro{\ToAddressWidth}
+% The following lengths are self-evident.
+% \begin{macrocode}
+\newlength{\FromAddressTopMargin}
+\newlength{\FromAddressLeftMargin}
+\newlength{\FromAddressHeight}
+\newlength{\FromAddressWidth}

+%
+% \subsection{Main setting commands}
+%
+% OK, we are ready to set up envelopes and labels.
+%
+% \begin{macro}{\SetEnvelope}
+% \changes{v1.2}{1997/07/14}{Added \cs{@biglabelfalse}}
+% The command "\SetEnvelope" has three parameters: optional top Margin,
+% width and height of the envelope.

+%
+% All options we did not declare above are probably the options for the
+% "graphics" package; let us send them there.
+% \begin{macrocode}
+\DeclareOption*{\PassOptionsToPackage{\CurrentOption}{graphics}}
+% \end{macrocode}
+%
+% \subsection{Default options}\label{sec:DefOpt}
+%
+% \changes{v1.1}{1996/07/08}{Fixed typo in "businessenvelope" option}

+\ExecuteOptions{printbarcodes,capaddress}
+\ExecuteOptions{nopswait,printreturnaddress,nopsautotray,nore}
+% \end{macrocode}
+%
+% \section{Configuration file}
+%
+% At this point we will look for the configuration file. This file is
+% named "envlab.cfg". The options declared in this file will supersede
+% the ones declared in Section~\ref{sec:DefOpt}, but will be in their
+% turn be superseded by the options explicitly defined when the package
+% is loaded.
+% \begin{macrocode}
+\InputIfFileExists{envlab.cfg}{%
+ \typeout{Loading configuration file envlab.cfg}}{%
+ \typeout{Configuration file envlab.cfg is not found}}
+% \end{macrocode}
+%
+% Now let us discuss the structure of the configuration file. We want it
+% to contain default options, and therefore to be loaded before the
+% "\ProcessOptions" command. On the other hand we want it to contain
+% some definitions that \emph{supersede} the ones in this package. The
+% hook "\AtEndOfPackage" helps to do this: we will just delay all
+% definitions until later.
+%
+% OK, let's construct an example of "envlab.cfg" file. The commands here
+% essentially repeat Section~\ref{sec:DefOpt}, but we want to be
+% foolproof\dots
+% \begin{macrocode}

+% The author explains his code in the following way:
+% \begin{quotation}
+% Here is a possible explanation:
+%
+% The clear removes operands from the PostScript stack, which has the
+% effect of reversing some actions from the *previous* bop. Unfortunately,
+% it reverses other important actions too (such as font size), but the
+% grestore seems to get these back. Then the desired @manualfeed, followed
+% by the ``bop'' for the beginning of page. The pair of 0's are used for
+% bop and are completely bogus. However, from what I could detect, 0's are
+% as good as anything. The values that DVIPS provides for bop seem to be
+% related to DVI page numbers.

+% I make no guarantee about the reliability of this solution, but initial
+% tests indicate it will work for my environment.

+% These macros process the address (actually, any string) according to the
+% USPS recommendations. Specifically, they:
+% \begin{itemize}
+% \item Strip dots (.) and commas (,) from the address unless they are
+% enclosed in brackets
+% \item Make all letters uppercase
+% \item Add 1pt space between letters
+% \item Add 1em space between words
+% \end{itemize}
+% An interesting question is whether we should de-accent accented
+% letters. USPS says nothing about it. In the present version accents
+% are \emph{not} stripped. However due to the scanning algorithm they
+% should be enclosed by brackets, like this:
+% "{\u S}andor {\c C}edi".

+% \section{Games with \texttt{.aux} file}
+%
+% The commands described in this section write something to the
+% |.aux| file, and thus change the way \EL\ treats the labels and
+% envelopes. Since the action is delayed till the |.aux| file is
+% processed, these commands affect only the labels automatically
+% extracted from the |letter| environment, and do not affect the
+% labels explicitly defined by the |\mlabel| commands in the main
+% file.
+%
+%
+% \changes{v1.2}{1996/09/07}{Added \cs{@@mlabel}}
+% \DescribeMacro{\@@mlabel}
+% The macro |\@@mlabel| stores the status of the |\@mlabel| as
+% determined by |\makelabels|. It is a no-op at the start.
+% If |\makelabels| redefines |\@mlabel|, we catch it through the
+% |\AtEndDocument| hook. Note that since |\makelabel| is allowed
+% only in the preamble, we are not in danger of redefining commands too
+% early.
+% \begin{macrocode}
+\let\@@mlabel=\@gobbletwo

+% printing mailing labels.

+% \section{Reimplementation of the \cs{opening} command}
+% \DescribeMacro{\re}
+% Some people like to put below the address information like
+% \begin{quote}
+% Re: our recent talk
+% \end{quote}
+% A way to do this is to include it in the address like this:
+% \begin{verbatim}
+% \begin{letter}{%
+% Dr.~Austin Tankel\\
+% Some University\\
+% Anytown, Pa 12345\\[1ex]
+% Re: Our recent talk}
+% \opening{Dear Austin:}
+% \end{verbatim}
+% However, this additional info will be put in the mailing label,
+% which is wrong. Here we describe a macro that works like this:
+% \begin{verbatim}
+% \begin{letter}{%
+% Dr.~Austin Tankel\\
+% Some University\\
+% Anytown, Pa 12345}
+% \re{Our recent talk}
+% \opening{Dear Austin:}
+% \end{verbatim}
+%
+%
+% Now, the implementation.
+% First, lets us check whether the option "re" is chosen (otherwise we
+% don't bother to redefine the commands):
+% \begin{macrocode}
+\if@EL@redefine@opening
+% \end{macrocode}
+%
+% \begin{macro}{\re}
+% \changes{v1.2}{1997/07/14}{Wrote new command}
+% \begin{macro}{\recontentents}
+% \changes{v1.2}{1997/07/14}{Wrote new command}
+% The command "\re" just defines "\recontents". Also, we initialize
+% "\recontents" to be initially empty
+% \begin{macrocode}
+ \newcommand*{\re}[1]{\def\recontents{#1}}%
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+%
+% \begin{macro}{\ReName}
+% \changes{v1.2}{1997/07/14}{Wrote new command}
+% By default it is just plain style ``Re: '' (note the space!)
+% \begin{macrocode}
+ \def\ReName{Re: }%
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\opening}
+% \changes{v1.2}{1997/07/14}{Reimplemented standard command
+% \cs{opening}}
+% Now we redefine the standard "\opening" command to include the "\re"
+% info. Here is the quote from the standard "letter"
+% class~\cite{letter}:
+% \begin{quotation}
+% Text is begun with the |\opening| command, whose argument
+% generates the salutation, as in
+%\begin{verbatim}
+% \opening{Dear Henry,}
+%\end{verbatim}
+% This should produce everything up to and including the
+% `Dear Henry,' and a |\par| command that follows.
+% Since there's a |\vfil| at the bottom of every page,
+% it can add vertical fill to position a short letter.
+% It should use the following commands:
+% \begin{itemize}
+% \item |\toname| : name part of `to' address.
+% Will be one line long.
+% \item |\toaddress| : address part of `to' address.
+% The lines separated by |\\|.
+% \item |\fromname| : name of sender.
+% \item |\fromaddress| : argument of current |\address|
+% declaration-- null if none. Should use standard institutional
+% address if null.
+% \item |\fromlocation| : argument of current |\location|
+% declaration--null if none.
+% \item |\telephonenum| : argument of current |\telephone|
+% declaration--null if none.
+% \end{itemize}
+% \end{quotation}
+% We just "\ReName" and "\recontents" here\ldots
+% \begin{macrocode}
+ \renewcommand*{\opening}[1]{\ifx\@empty\fromaddress
+ \thispagestyle{firstpage}%
+ {\raggedleft\@date\par}%
+ \else % home address
+ \thispagestyle{empty}%
+ {\raggedleft\begin{tabular}{l}\ignorespaces
+ \fromaddress \\*[2\parskip]%
+ \@date \end{tabular}\par}%
+ \fi
+ \vspace{2\parskip}%
+ {\raggedright \toname \\ \toaddress \par}%
+ \ifx\@empty\recontents\relax
+ \else
+ {\raggedright \ReName \recontents \par}%
+ \fi
+ \vspace{2\parskip}%
+ #1\par\nobreak}%
+% \end{macrocode}
+% \end{macro}
+%
+% Now we close \cs{if@EL@redefine@opening}:
+% \begin{macrocode}
+\fi
+% \end{macrocode}
+%
+% And the last line:
