+\section{Introduction}
+\label{sec:Intro}
+
+The standard |\makelabels| command in the \LaTeXe\ |letter.cls|
+document class typesets labels on Avery 5352 sheets. A typical user
+may want more. \EL\ redefines |\makelabels| in\footnote{hopefully}
+a more useful and customizable way. \EL:
+\begin{itemize}
+\item Typesets mailing labels or envelopes on a number
+ of pre-defined label sheets \emph{or} envelopes.
+\item Can be easily configured for any customized label or envelope
+ sizes. The rule of thumb is: if you printer can print this, \EL\ can
+ typeset this.
+\item Can optionally print barcodes and/or process addresses according
+ to the United States Postal Service Rules.
+\item Allows you to include your logo in the return address.
+\item Painlessly interacts with mail merging packages such as
+ |mailing|.
+\item Does not require special fonts for address and barcodes
+ printing. The typesetting is implemented with standard fonts and
+ \LaTeX\ |\rule| commands.
+\end{itemize}
+
+This package was written with US mailing standards in mind. This is
+not a reflection of the author's americanocentrism: US standard was
+only one I had official documents about. If you want to add your
+national standards, please contact me with pointers to the
+corresponding documents.
+
+This document describes the basic usage of the package. More
+sophisticated users would want to typeset and browse |envlab.dtx| as
+well.
+
+\section{Installation}
+\label{sec:Install}
+
+The distribution of this package includes the following files:
+\begin{enumerate}
+\item |envlab.dtx|---fully documented program,
+\item |envlab.ins|---\DS\ instruction module,
+\item |elold.ins|---\DS\ instruction module for older
+ versions of \DS,
+\item |elguide.tex| (this file)---User Guide,
+\item |readme.|\emph{version\_number}---ReadMe file.
+\end{enumerate}
+To install the package
+\begin{enumerate}
+\item \LaTeX\ the file |envlab.ins|\footnote{If your |docstrip.tex| is
+ earlier than version 2.3, use |elold.ins| instead of
+ |envlab.ins|.}. It will produce three files: |envlab.drv|,
+ |envlab.sty| and |envlab.cfg|.
+\item (Optional) Look at the file |envlab.cfg| and change it
+ accordingly to your taste (see Section~\ref{sec:Cust}).
+\item Move the files |envlab.sty| and |envlab.cfg| to the
+ \LaTeX\ search path
+\item Produce the documentation by \LaTeX ing the files |elguide.tex|
+ and (optional) |envlab.drv|.
+\item Enjoy!
+\end{enumerate}
+
+
+\section{Usage}
+\label{sec:Usage}
+
+
+\subsection{The basics}
+\label{sec:Basics}
+
+The package \EL\ is intended to be used with the \LaTeXe\ |letter|
+document class and similar custom classes. The standard document class
+defines the environment |letter|, which, among other things, writes to
+the main |.aux| file the information about mailing address. \EL\
+retrieves and typesets this information. In general one should not use
+\EL\ with document classes that do not provide this information. The
+package types an error message if it cannot find the |makelabels|
+command in the class it is called from\footnote{If you want to create
+ a custom letter class to be used with \EL, take care to write
+ commands \cs{startlabels} and \cs{mlabel}\marg{from-address}\marg{to-address}
+ to the |.aux| file. Also
+ define a \cs{makelabels} command. The latter can do
+ anything---\EL\ will redefine it anyway, but the package needs to see
+ \cs{makelabels} defined at the start up}.
+
+
+There are three ways to use \EL:
+
+
+
+\subsubsection{Automatic generation of envelopes or labels}
+ \begin{decl}
+ |\makelabels|
+ \end{decl}
+ Put in the preamble of your document:
+ |\usepackage|\oarg{options}|{envlab}| and |\makelabels|. The package
+ will generate envelopes or labels at the end of your document, ready
+ to be printed. An example of such usage is shown on
+ Fig.~\ref{fig:Auto}.
+
+ An interesting extension of this method is the use of \EL\ with
+ mail-merge packages. If such packages generate |letter|
+ environments, then \EL\ will happily produce envelopes or labels for
+ them. I tested \EL\ with the \mailing\ package available at
+ CTAN with excellent results. See an example on Fig.~\ref{fig:Merge}.

+
+\subsubsection{Manual generation of envelopes or labels}
+\begin{decl}
+ |\startlabels|, |\mlabel|\marg{from-address}\marg{to-address}
+\end{decl}
+Sometimes you need to generate only mailing labels or envelopes, but
+not letters themselves. In this case prepare a separate document of
+|letter| document class. Put in the preamble of your document
+|\usepackage|\oarg{options}|{envlab}| and |\makelabels|, and in the
+body of your document the command |\startlabels|\footnote{It sets up
+ page parameters for envelopes and letters}, and commands
+|\mlabel|\marg{from-address}\marg{to-address} for each label you want
+to generate (see Fig.~\ref{fig:Manual})

+
+
+\subsubsection{Printing of return labels}
+\begin{decl}
+ |\printreturnlabels|\marg{number}\marg{text}
+\end{decl}
+
+Sometimes you need to print only return labels. To print \marg{number}
+of labels with the \marg{text} on each use the command
+|\printreturnlabels|\marg{number}\marg{text}. It is better to put it in
+a separate document (see Fig.~\ref{fig:Return}).

+
+\subsection{Sizes of labels and envelopes}
+
+\EL\ package makes a distinction between envelopes and labels. The
+differences are:
+\begin{itemize}
+ \item Envelopes are printed on separate pages, labels are printed
+ several per page
+ \item Envelopes might have return address, labels might not
+ \item Envelopes are rotated by default, labels are never rotated
+\end{itemize}
+
+

+ |businessenvelope|,
+ |executiveenvelope|,
+ |bookletenvelope|,
+ |personalenvelope|,\\
+ |c6envelope|,
+ |c65envelope|,
+ |c5envelope|
+\end{decl}
+\EL\ knows about a number of standard envelopes. The options listed in
+Table~\ref{tab:Env} are used to typeset the addresses for envelopes
+with the given width and height. For example, if you have
+$9.5''\times4.125''$ envelopes, use the command
+|\usepackage[businessenvelope]{envlab}|.
+
+\begin{table}[tbp]
+ \begin{center}
+ \leavevmode
+ \begin{tabular}{ccc}
+ \hline
+ Package option & Width & Height\\
+ \hline
+ businessenvelope & 9.5$''$ & 4.125$''$\\
+ executiveenvelope & 7.5$''$ & 3.875$''$\\
+ bookletenvelope & 10.5$''$ & 7.5$''$\\
+ personalenvelope & 6.5$''$ & 3.625$''$\\
+ c6envelope & 162 mm & 114 mm\\
+ c65envelope & 224 mm & 114 mm\\
+ c5envelope & 229 mm & 162 mm\\
+ \hline

+ \label{tab:Env}
+ \end{center}
+\end{table}
+
+\begin{decl}
+ |\SetEnvelope|\oarg{top margin}\marg{width}\marg{height}
+\end{decl}
+If your envelope is not listed in Table~\ref{tab:Env}, put in the
+preamble of your document the command
+|\SetEnvelope|\marg{width}\marg{height}\footnote{The optional first
+ argument of this command is described in Section~\ref{sec:Print}}.
+Its arguments are dimensions of your envelope (together with the
+units!). For example, if you have $8''\times4''$ envelopes, use the
+command |\SetEnvelope{8in}{4in}|.
+
+\begin{decl}
+|avery5160label|,
+|avery5161label|,
+|avery5162label|,\\
+|avery5163label|,
+|avery5164label|
+\end{decl}
+\EL\ knows also about a number of commercially available labels.
+They are listed in Table~\ref{tab:Lab}. The dimensions $W$ and $H$ are
+the label total width and height, $t$ and $l$ are the distance between
+the edge of the paper and the label (see Fig.~\ref{fig:Labels}). The
+numbers $N_c$ and $N_r$ are correspondingly the numbers of columns and
+rows of labels on a sheet.

+command is completely analogous to the command |\SetEnvelope|
+described above.
+
+
+\subsection{Printing details}\label{sec:Print}
+
+\EL\ typesets envelopes or sheets of labels just after the main text
+of all letters in the documents. Most printers that have paper tray
+and manual feeding slot use manual slot if it is not empty and tray
+otherwise. When printing envelopes or labels on such printers, you
+wait until the text of letters is printed, and then insert envelopes
+or label sheets one by one in the manual feeding slot.
+
+\begin{decl}
+ |\AtBeginLabels|\marg{Printer specific commands}\\
+ |\AtBeginLabelPage|\marg{Printer specific commands}
+\end{decl}
+However some printers have several paper trays and even paper trays
+for envelopes. Moreover, sometimes the switching between trays can be
+performed automatically by software commands. If you know such
+commands for your printer and know how to insert them in the |.dvi| file
+(e.g. through |\special|s), you can use the hook
+|\AtBeginLabels|. Put the printer specific commands in the
+argument of |\AtBeginLabels|. If you succeed, please e-mail me these
+commands and the specifications of your printer, so I can include them
+in the future releases of \EL. \NEWfeature{Version 1.1} Note that the
+command |\AtBeginLabels| is cumulative: if you use it several times in
+the same document, the new commands will be appended without overwriting
+the previous definitions. \NEWfeature{Version 1.1}. The command
+|\AtBeginLabelPage| works in the same way, but its argument will be
+inserted at the beginning of each \emph{page} of \EL\ output, i.e. before
+printing each envelope or label sheet.
+
+\begin{decl}
+ |pswait|, |nopswait|
+\end{decl}
+\NEWfeature{Version 1.1}
+If you use \dvips, you can ask it to switch your printer to manual
+mode just before printing envelopes and labels. The printer will print the
+main body of the letter(s) using the paper tray, and then stop, waiting for
+envelopes or label sheets to be fed in the manual slot. The option
+|pswait|, based on the code by \emph{William Slough}
+\texttt{<cfwas@eiu.edu>},
+inserts the corresponding \PS\ |special|s in your output.
+The option |nopswait| (default) suppresses this behavior.
+
+\begin{decl}
+ |\PSwait|
+\end{decl}
+\NEWfeature{Version 1.1} William Slough's code can be useful in
+other situations when you need to switch to manual mode in the
+middle of the document. The command |\PSwait| inserts the
+corresponding \PS\ code in the \dvips\ output. (An attentive reader
+has probably already guessed that the |pswait| option is implemented
+through the command |\AtBeginLabels{\PSwait}|).
+
+Note that there are differences in the handling of the text close to paper
+edges from printer to printer. Since envelopes and label sheets have text
+near the edges, you might need to tune the offsets. For labels you can use
+the command |\SetLabel| to do this. The optional first argument of the
+command |\SetEnvelope| sets the distance between the leading edge of
+``logical paper'' and the physical leading edge of the envelope (0 pt by
+default).
+
+\begin{decl}
+ |rotateenvelopes|, |norotateenvelopes| \\
+ Options for \graphics\ package
+\end{decl}
+Usually envelopes are printed in the landscape mode, i.e. rotated by
+$90^\circ$. The package options |rotateenvelopes| (default) and
+|norotateenvelopes| control the rotation. Note that if you want to
+rotate envelopes, you need the standard package \graphics\
+installed on your system. Also, you need a |dvi| driver that
+understands rotation commands of the \graphics\ package. (I
+think currently only \dvips\ does this). The package
+\graphics\ is called internally by \EL. If you need to pass
+specific options to the \graphics\ package, include it in the
+list of options of \EL. For example, the command
+|\usepackage[personalenvelope,dvips]{envlab}| calls \graphics\
+with the option |dvips|.
+
+\begin{decl}
+ |centerenvelopes|, |leftenvelopes|,
+ |rightenvelopes|,\\
+ |customenvelopes|, |\EnvelopeLeftMargin|
+\end{decl}
+Most of manual feeding slots accept non-standard paper (like
+envelopes) \emph{centered}. However there are some printers that
+require non-standard paper to be pushed to the left or right end of
+the slot. The package options |centerenvelopes| (this is the default
+option), |leftenvelopes|, |rightenvelopes| and |customenvelopes|
+control the position of the envelope with respect to the slot. The
+first three options are self-explanatory. The fourth gives the control
+over the envelope positioning to the user. If you choose this option,
+you must set the length |\EnvelopeLeftMargin| before printing the
+envelopes. For example to shift the envelope for $2''$ from the left
+edge use |\setlength{\EnvelopeLeftMargin}{2in}|
+
+\begin{decl}
+ |LabelOffsetRow|, |LabelOffsetCol|,\\
+ |\FirstLabel|\marg{Row}\marg{Col}
+\end{decl}
+Sometimes you need to print labels on a partially used sheet. The
+counters |LabelOffsetRow| and |LabelOffsetCol| (default values 1) set
+the position of the first label to print. You can change them using
+the |\setlength| command. \NEWfeature{Version 1.1} Alternatively, you can
+use the command |\FirstLabel|\marg{Row}\marg{Col} to set both counters
+simultaneously. For example, the command |\FirstLabel{3}{2}| causes \EL\
+to start printing labels beginning with the second label in the third
+row. Note that labels are printed row by row (\emph{not} column by
+column, like in the standard \LaTeXe\ |letter| class).
+
+
+\subsection{Formatting of the address (barcodes and capitalization)}
+
+In the United States (and many other countries as well) the mailing
+pieces are sorted by machines. This process is greatly facilitated if
+the addresses typesetting is enhanced for machine readability.
+
+
+USPS standards \cite{Pub25} establish two ways for making the addresses
+machine readable: barcodes and special printing of addresses for
+optical character recognition (OCR) devices. In principle any method
+would be sufficient, but it seems reasonable to play it safe using
+\emph{both} methods. Therefore \EL\ by default both prints barcodes
+and prepares addresses for OCR. This behavior can be controlled
+through package options.
+
+Note that only ``To-Address'' should be machine-readable. The return
+address can be formatted more freely. You can, for example, include
+your logo in the \emph{return} address (see Section~\ref{sec:Cust})
+
+\begin{decl}
+ |printbarcodes|, |noprintbarcodes|
+\end{decl}
+The addresses in the US contain ``zipcodes''---strings of five digits
+(5-code) or 9 digits divided by dash (5+4 code). The 5+4 code is
+actually a detalization\footnote{There is an even finer detalization
+ provided by the so called DPC numbers \cite{Pub25}. \EL\ does not
+ support it yet}, so the zipcode 12345-6789 can be written as just
+12345. This code is converted into a series of long and short bars and
+printed on a label or envelope. If the option |printbarcodes|
+(default) is selected, \EL\ tries to extract zipcode from the address
+and print it. It defines zipcode as a sequence of digits that:
+\begin{enumerate}
+\item Has no characters other than digits and dashes (-) inside it
+\item Has no groups in braces (|{}|)inside it and is not braced itself
+\item \label{item:Last} Is the last in the address field
+\end{enumerate}
+The option |noprintbarcodes| suppresses the typesetting of barcodes.
+
+\begin{decl}
+ |alwaysbarcodes|, |noalwaysbarcodes|
+\end{decl}
+Sometimes the rule~\ref{item:Last} is too harsh. Consider, for example,
+the following address:
+\begin{quote}
+ Mr. A. B. User\\
+ 32 Omega Road\\
+ Palo Alto Ca 12345\\
+ USA
+\end{quote}
+Obviously it has a zipcode, however \EL\ normally will not see it. The
+option |alwaysbarcodes| lifts this restriction, and \EL\ typesets barcodes
+for the last number met in the address even if it is followed by some other
+characters. Be careful with this option! If you select it, all addresses
+must actually have zipcodes. Otherwise \EL\ will happily convert to bars a
+street or apartment number.
+
+This option is especially useful if the addresses are not typed in
+manually, but are prepared by some mail merge program like
+\mailing\ package. Then they can contain spaces at the end, and
+\EL\ will not recognize zipcodes unless |alwaysbarcodes| is selected.
+The option |noalwaysbarcodes| (default) suppresses this behavior.
+
+\begin{decl}
+ |capaddress|, |nocapaddress|
+\end{decl}
+To facilitate OCR \EL\ typesets addresses in \textsf{\large 12pt sans
+ serif} font. The machine readability of the addresses is increased
+if the following recommendations of US Postal service are followed:
+\begin{itemize}
+\item Converting the addresses to uppercase
+\item Stripping punctuation from the addresses
+\item Inserting 1 pt kern between the letters
+\end{itemize}
+The result looks rather ugly for human eye. However, it is intended not for
+humans, but for machines. We will call this processing \emph{address
+ capitalization}. \EL\ performs capitalization of the
+``To-addresses'' automatically if the option |capaddress| (default) is
+selected. The option |nocapaddress| suppresses capitalization of the
+addresses.
+
+If you decide to capitalize the addresses, be careful with the
+accented letters. Since \EL\ processes the address letter by
+letter\footnote{Rather, token by token}, it tries to insert kern
+between |\"| and |u| in the word |M\"uller| causing an
+error. Therefore all accented letters should be enclosed in
+braces. The correct way to typeset Herr.~M{\"u}ller is
+|Herr.~M{\"u}ller|\footnote{I probably should strip all accents since
+ they might confuse OCR. However USPS says nothing about accents, and
+ I decided to preserve them.}.
+
+\subsection{Printing of return addresses}
+
+
+\begin{decl}
+ |printreturnaddress|, |noprintreturnaddress|
+\end{decl}
+\NEWfeature{Version 1.1}
+The return addresses are printed on the envelopes if the package option
+|printreturnaddress| (default) is chosen. Alternatively, the package
+option |noprintreturnaddress| suppresses the printing of the return
+address. Section~\ref{sec:Cust} describes how to customize your return
+address.
+
+
+\section{Customization}
+\label{sec:Cust}
+
+\begin{decl}
+ |\returnaddress|
+\end{decl}
+Many people and companies want to print their logos on the
+envelopes. You can include any image in your return address. The macro
+|\returnaddress| controls the contents of the ``From-address'' field
+on your envelope. \EL\ takes it from the |\address| command in your
+document. However you can easily redefine it. For example, if the file
+|mylogo.eps| contains your logo, you put in the preamble
+|\renewcommand{\returnaddress}{\protect\includegraphics{mylogo}}| to
+customize your envelopes. If you want return labels with your logo,
+use command like
+|\printreturnlabels{180}{{\protect\includegraphics{mylogo}}|.
+\NEWdescription{Version 1.1} You can
+include both logos and textual information into the |\returnaddress| macro.
+While customizing return address, it is useful to know that
+\LaTeX\ |letter| document class stores the contents of the |\address|
+command in the |\fromaddress| macro, so the default definition of the
+return address implemented in \EL\ is
+|\renewcommand{\returnaddress}{\fromaddress}|.
+
+\begin{decl}
+ Customization of lengths
+\end{decl}
+All lengths (heights, widths, margins) are user-customizable. Consult
+the file |envlab.dtx| for their definitions and use.
+
+\begin{decl}
+ |envlab.cfg|
+\end{decl}
+If you use \EL\ for some time, you probably would have a number of
+options and commands that you execute in most documents prepared with
+the package. You can save the typing by putting such commands in the
+configuration file |envlab.cfg|. A sample configuration file is
+included in the \EL\ distribution. You are free to hack it in any way
+you like\footnote{\emph{Important:} |envlab.cfg| is the only file you
+ should modify. You are \emph{not} allowed to modify any other files
+ in the \EL\ distribution.}. This file consists of two parts:
+|\ExecuteOptions|\marg{options} and
+|\AtEndOfPackage|\marg{customization commands}. The options listed in
+the first part supersede the default options of \EL. However the
+options explicitly listed as the arguments of the |\usepackage|
+command supersede the options in the configuration file. The commands
+listed in the second part of the configuration file---as the arguments
+of the |\AtEndOfPackage| command---supersede all definitions in the
+package itself. Therefore by hacking |envlab.cfg| you can completely
+change the behavior of the package without modifying \EL.
+
+
+\section{Bugs and limitations}
+\label{sec:Bugs}
+
+\NEWdescription{Version 1.1}
+The most important limitation of \EL\ is related to an essential
+limitation of \TeX\ itself. People usually want their envelopes printed
+rotated $90^\circ$, so the envelopes are inserted in the printed by the
+short side. Unfortunately \TeX\ was not designed with the text rotation
+in mind. Therefore ``basic'' \TeX\ does not allow to typeset envelopes in
+this manner. The standard \LaTeXe\ package \graphics\ uses \PS\ to add
+this functionality to \TeX. \EL\ uses \graphics\ internally if the option
+|rotateenvelopes| (default) is in effect. Therefore to typeset rotated
+envelopes you need \graphics\ and either a \PS\ printer or \gs. Otherwise
+use |norotatenvelopes| option if your printed can process envelopes
+inserted by the long side. I understand that there is a problem with
+printing rotated text on non-\PS\ printers. Probably the authors of
+|dvi| drivers should be urged to address it.
+
+\NEWdescription{Version 1.1}
+\EL\ thinks that all options it cannot understand belong to the
+\graphics\ package and sends them there. Therefore if you misspell
+an option of the \EL\ package, you will receive an error message from the
+\graphics\ package rather than from \EL.
+
+
+Please send bug reports to |boris@plmsc.psu.edu|. You can find
+experimental versions of \EL\ at my homepage
+(|http://planck.psu.edu/~boris|).
+
+
+\section{Legalese}
+
+The package \EL\ is provided ``as is'' and comes with absolutely no
+warranty of any kind, either expressed or implied, including, but not
+limited to, the implied warranties of merchantability and fitness for
+a particular purpose. The entire risk as to the quality and
+performance of the program is with you. Should the program prove
+defective, you assume the cost of all necessary servicing, repair or
+correction.
+
+In no event unless required by applicable law will the author of the
+program be liable to you for damages, including any general, special,
+incidental or consequential damages arising out of any use of the
+program or out of inability to use the program (including but not
+limited to loss of data or data being rendered inaccurate or losses
+sustained by you or by third parties as a result of a failure of the
+program to operate with any other programs), even if such holder or
+other party has been advised of the possibility of such damages.
+
+In particular, while every effort was made to provide typesetting of
+mailing pieces accordingly to the United States Postal Service
+recommendations, the author of the package does not warrant neither
+successful delivery of mail nor granting of mailing discounts in the
+USA or any other countries.
+
+
+
+
+\EL\ package is covered by the same license as the current \LaTeXe\
+package (see the files |legal.txt| and |modguide.tex| in the \LaTeXe\
+distribution).
