+% \begin{abstract}
+% A \LaTeX\ style to print
+% a regular grid of ragged-right labels on a page, suitable for sheets
+% of labels
+% which can be fed through a laser printer. Macros are provided to
+% allow easy input of names and addresses in a form free of \TeX\ markup.
+% Equally useful is a feature for making multiple copies of a single
+% label, e.g., return address stickers to go with the labels.
+% \end{abstract}
+%
+% \section{Generating Style Files and Documentation}
+% Automatic generation of the style files uses the command line
+% \begin{center} |latex labels.ins| \end{center}
+% to create the files |labels.sty| (for \LaTeX{}2e)
+% and |olabels.sty| (for \LaTeX{}209). Usage in the preamble section of
+% a \LaTeX{} source file is
+% |\input{olabels.sty}| for \LaTeX{}209 and
+% |\usepackage{labels}| for \LaTeX{}2e. Backward compatibility with
+% \LaTeX{}209 may be removed suddenly in some future release.  Please
+% observe that documentation is created by the command line
+% |latex labels.dtx|,
+% and no provision is made to produce documentation via \LaTeX{}209.
+%
+% \section{Usage}
+% This style file was written to produce a sheet of labels which can be
+% xeroxed onto \textsf{Avery brand} 5360 sticky-label material. This label
+% material is made for a xerox machine and it has 7 rows and 3
+% columns of labels on |letterpaper|. It works for other label
+% layouts as well. In particular, the defaults for the most popular
+% paper sizes |letterpaper| and |a4paper| are  $7$
+% rows by $3$ columns and $8$ rows by $3$ columns, respectively.
+%
+% Other uses include production of disk labels, book labels, shipping
+% labels, name tags, door cards, photo galleries and compact membership
+% lists.
+%
+% The task of this package is to produce a rectangular grid of
+% items on a sheet of paper, with each item centered in its grid area.
+% It really doesn't matter what goes in the grid area: text, graphics or
+% any \LaTeX{} construct. For example, you might use the |fancybox|
+% package to produce oval-box or shadow-box name tags for a conference.
+%
+% \subsection{Paper Sizes}
+% The paper size is supplied by the document options for the class.
+% The European default is |a4paper| and the American default is
+% |letterpaper|, $8.5\times 11$-inch, inherited from the
+% class file, e.g., |article.cls|.
+% \begin{description}
+%\item[\textbf{a4paper}] 297mm by 210mm.
+%\item[\textbf{a5paper}] 210mm by 148mm.
+%\item[\textbf{b5paper}] 250mm by 176mm.
+%\item[\textbf{letterpaper}] 11in by 8.5in.
+%\item[\textbf{legalpaper}] 14in by 8.5in.
+%\item[\textbf{executivepaper}] 10.5in by 7.25in.
+%\end{description}
+%
+% \subsection{Label Stock Sizes}
+% A number of different label stocks are available for xerox machines
+% and laser printers. The typical stock has $m$ rows and $n$ columns
+% with various gutters on the page. Below is a table of \textsf{Avery}
+% products that are in common use in America.

+%
+% Another common label stock is \textsf{Dennison} 37-141, having 3 columns
+% and 8 rows of $1\frac38\times2\frac78$ gutterless labels on
+% letterpaper. The information by the manufacturer is not precisely
+% correct, because the first column \emph{is} exactly $2\frac78$ inches
+% wide, but the other two are $2\frac{13}{16}$ inches wide.
+%
+% A common problem with implementing this package on a new label stock
+% is precision of the laser printer, which prints the master, and the
+% xerox machine which prints the master onto the label stock. Some of
+% the above are for direct use on a laser printer, which removes one
+% source of error, but replaces it by the possibility that the label
+% stock will jam in the laser printer!
+%
+% \subsection{Customizing for Other Labels: the traditional method}
+% It is very likely that the label stock will be different than Avery 5360.
+% Generally, it is necessary to tailor the source file to a particular type
+% of label.
+% The lines below may be placed in the preamble and edited to suit
+% the application and the actual printer used for output.
+%  \begin{verbatim}
+%   \documentclass[12pt]{article}
+%   \usepackage{labels}
+%   \LabelCols=3%         Number of columns of labels per page
+%   \LabelRows=7%         Number of rows of labels per page
+%   \LeftBorder=8mm%      Space added to left border of each label
+%   \RightBorder=8mm%     Space added to right border of each label
+%   \TopBorder=9mm%       Space to leave at top of sheet
+%   \BottomBorder=2mm%    Space to leave at bottom of sheet
+%   \begin{document}%     End of preamble
+%  \end{verbatim}
+% These controls can also be issued after the beginning of the document,
+% but the results are undefined unless the following example is
+% followed, which uses the |\LabelSetup| control sequence:
+%  \begin{verbatim}
+%   \begin{document}%     End of preamble
+%   \LabelCols=3%         Number of columns of labels per page
+%   \LabelRows=7%         Number of rows of labels per page
+%   \LeftBorder=8mm%      Space added to left border of each label
+%   \RightBorder=8mm%     Space added to right border of each label
+%   \TopBorder=9mm%       Space to leave at top of sheet
+%   \BottomBorder=2mm%    Space to leave at bottom of sheet
+%   \LabelSetup%          Invoke new settings
+%  \end{verbatim}
+% For example,  \emph{your}
+% grid maybe has only two columns of ten labels each, requiring the
+% first two variables to be reset. The gutter areas on the label
+% material dictate how to set the other parameters.
+% Personal adjustments can be made for the amount of white space around
+% each label.
+%
+% The printer driver is expected to print the page
+% \emph{exactly} as it should in vanilla \TeX, i.e., with the origin of
+% the page down one inch and right one inch from the top left hand
+% corner of the paper. If it doesn't, adjust the printer driver
+% parameters.
+%
+% A common problem with printers is that label output is
+% extra wide, requiring printing onto the very edges of the
+% paper. Some printers may not be able to maintain print quality
+% all the way to the edges of the paper.
+% Adjust the parameters |\LeftBorder|, |\RightBorder|, |\TopBorder|,
+% |\BottomBorder| as outlined below to solve this problem.
+%
+% First of all, |\TopBorder| is not the white space at the top of the
+% page, but the amount of space to leave at the top so that the first
+% label is centered on its grid. This number is determined by trial and
+% error using the actual printer, xerox machine and label stock to be
+% used in the production run.
+%
+% The second value |\BottomBorder| is determine empirically also, so
+% that the labels are all centered on their grids. A mathematical
+% formula to be satisfied is
+%\def\AA{\mbox{\texttt{paperheight}} - \mbox{\texttt{TopBorder}} -
+% \mbox{\texttt{BottomBorder}}}
+%\def\BB{\mbox{\texttt{LabelRows}}}
+%$$ \mbox{\texttt{Label Height}} = \frac{\AA}{\BB} $$
+% The values |\LeftBorder| and |\RightBorder| are amounts of white space
+% to be added to the left and right of the actual label area so that the
+% label itself does not smash into the edge of the grid. The actual
+% label width is considerably smaller than the grid width (physical
+% width of the label stock). It is determined by the formula
+%\def\AA{\mbox{\texttt{paperwidth}}}
+%\def\BB{\mbox{\texttt{LabelCols}}}
+%\def\CC{\mbox{\texttt{LeftBorder}}}
+%\def\DD{\mbox{\texttt{RightBorder}}}
+%$$ \CC + \mbox{\texttt{Label Width}} + \DD = \frac{\AA}{\BB}$$
+% Normally, the left and right white space dimensions are the same, but
+% there can be exceptions. It is best to determine the dimensions
+% empirically on the actual equipment to be used in the production run.
+% Visual guides from a |dvi| viewer can help, but be aware that the
+% laser printer may fail to print near the edge and the xerox machine
+% may either enlarge or shrink the image onto the label stock.
+%
+% An optional \textit{grid overlay} can be produced with the label output for
+% testing purposes by the preamble control sequence |\LabelInfotrue|.
+% Most |dvi| viewers are capable of showing the entire test grid. Once
+% printed, the overlay can be compared with the actual label stock to
+% see if the borders are in the proper place. By adjusting parameters,
+% the master copy off the laser printer should be able to pass through the
+% xerox machine automatically.
+%
+% \subsection{Customizing for Other Labels: the new method}
+% 
+% One of the deficiencies of the method described above it that it is
+% unable to cope well with labels having spaces between them, and the
+% dimensions specified are not the natural ones which one would want
+% to measure.  If the package option |newdimens| is given (and this
+% only works for users of \LaTeXe), then we can
+% give page parameters in a far more flexible manner as follows, where
+% these dimensions are suitable for Avery L7160 labels:
+%  \begin{verbatim}
+%   \documentclass[a4paper,12pt]{article}
+%   \usepackage[newdimens]{labels}
+%   \LabelCols=3%             Number of columns of labels per page
+%   \LabelRows=7%             Number of rows of labels per page
+%   \LeftPageMargin=7mm%      These four parameters give the
+%   \RightPageMargin=7mm%       page gutter sizes.  The outer edges of
+%   \TopPageMargin=15mm%        the outer labels are the specified
+%   \BottomPageMargin=15mm%     distances from the edge of the paper.
+%   \InterLabelColumn=2mm%    Gap between columns of labels
+%   \InterLabelRow=0mm%       Gap between rows of labels
+%   \LeftLabelBorder=5mm%     These four parameters give the extra
+%   \RightLabelBorder=5mm%      space used around the text on each
+%   \TopLabelBorder=5mm%        actual label.
+%   \BottomLabelBorder=5mm%   
+%   \begin{document}%         End of preamble
+%  \end{verbatim}
+% (The |\LabelSetup| form can also be used, as above.)  Thus the four
+% |\...PageMargin| parameters and the |\InterLabel...| paramenters
+% define the location of the physical labels on the page, and the
+% four |\...LabelBorder| parameters define how the space on each label
+% is to be used.
+% 
+% As before, the printer driver is expected to print the page
+% \emph{exactly} as it should in vanilla \TeX, i.e., with the origin of
+% the page down one inch and right one inch from the top left hand
+% corner of the paper.  If it doesn't, adjust the printer driver
+% parameters.
+%
+% We now describe how the locations of the labels are determined, as
+% we did before.  The label height and label width are given by the
+% formul\ae:
+% $$\begin{array}{l}
+%   \mbox{\texttt{LabelRows}}\times\mbox{\texttt{Label height}} +
+%   (\mbox{\texttt{LabelRows}}-1)\times\mbox{\texttt{InterLabelRow}} =\\
+%   \qquad\mbox{\texttt{paperheight}} - \mbox{\texttt{TopPageMargin}} -
+%   \mbox{\texttt{BottomPageMargin}}
+% \end{array}$$
+% and
+% $$\begin{array}{l}
+%   \mbox{\texttt{LabelColumns}}\times\mbox{\texttt{Label width}} +
+%   (\mbox{\texttt{LabelColumns}}-1)\times\mbox{\texttt{InterLabelColumn}} =\\
+%   \mbox{\texttt{paperwidth}} - \mbox{\texttt{LeftPageMargin}} -
+%   \mbox{\texttt{RightPageMargin}}
+% \end{array}$$
+% Then, within each label, the label text is vertically centered in a
+% box which is indented |\TopLabelBorder| from the top of the label,
+% |\BottomLabelBorder| from the bottom, |\LeftLabelBorder| from the
+% left and |\RightLabelBorder| from the right.
+% 
+% It is an error if $\mbox{\texttt{TopLabelBorder}} +
+% \mbox{\texttt{BottomLabelBorder}} \geq \mbox{\texttt{Label
+% height}}$, and similarly for the width; the results in such cases
+% may be unpredictable.
+% 
+% Note that the |\LabelInfoTrue| function only draws the outlines of
+% the physical labels; see below for information on |\LabelGridtrue|.
+% 
+% \subsection{Using an External Label source File}
+% The simplest form of input is very
+% short, as in the following example:
+% \begin{verbatim}
+%   \documentclass{article}
+%   \usepackage{labels}
+%   \begin{document}
+%   \labelfile{names.dat}
+%   \end{document}
+% \end{verbatim}
+% where |names.dat| contains names and address in
+% \textit{plain format}. Source files in plain format may contain
+% extra blank lines (only one blank line between labels is required).
+% Sort fields should begin with |%| in column $1$, so they don't print
+% as part of the label. Leading and trailing blanks on lines are
+% ignored. The formfeed character Ctrl-L seems to be acceptable in the
+% source. A formfeed is not
+% ignored, even if it appears at the end of the file. For example, if
+% |^L| appears on a line by itself, then it either produces an empty
+% label or else a blank line, if it happens to be in a group of label
+% lines. The label data commonly appears on lines, flush left, with no
+% intervening blank lines, because a blank line signals a new label. To
+% purposely create blank labels, as for filling out a page of labels,
+% see the control sequence |\skiplabels{#1}|, \textit{infra}. The actual
+% text in the external file may contain \LaTeX{} markup controls. This
+% includes comment marks |%|, which will be ignored during typesetting.
+%
+%\section*{Source File Creation and Sorting}
+% Most mailing lists that already exist can be edited to create an
+% acceptable list in the proper format. If long lines are to wrap,
+% then force all the material to be wrapped onto one line in the source.
+% Otherwise, break the material into lines of the length desired.
+% Any special items in a mailing label can be coded in \LaTeX{}, e.g.,
+% foreign names with accented characters, trademarks and font size
+% changes.
+%
+% Generally, raw sources have to be searched for special \LaTeX{}
+% controls and brought up to standard. The characters below may be
+% used in a source file for writing \LaTeX{} code. Generally, a raw
+% source has to be manually stripped of these characters.
+%\begin{verbatim}
+%Double quote  \"     Hash (number) \#     Underscore    \_
+%Dollar        \$     Percent       \%     Ampersand     \&
+%Less than     \<     Greater than  \>     Vertical bar  \|
+%Commercial at \@     Backslash     \\     Circumflex    \^
+%Left brace    \{     Right brace   \}     Tilde         \~
+%\end{verbatim}
+%
+% A typical comment line might start with |%| and then |^L| (ctrl-L)
+% followed by a sort key (e.g., the zip code or last name). The |emacs|
+% editor supports a method of sorting such records, thereby rearranging
+% the source file into a new label order. The method:
+% \begin{itemize}
+% \item
+% Mark the whole file as a region: |^[<| goes to the top of file, then
+% |^@| sets mark; follow by |^[>| to mark the whole file.
+%\item
+% Invoke |emacs|'s |sort-pages| external routine as follows. Press |^[x|
+% then enter |sort-pages| and press return. The region marked will be
+% sorted on the first line of each page, with a page delimited by |^L|.
+% For some |emacs| versions, the first line of the marked block has to
+% be empty, in order to produce a successful sort.
+% \end{itemize}
+%
+% \section*{General purpose \LaTeX{} Source}
+%
+% To set up a general-purpose \LaTeX{} source file, use
+% the following source, which prompts for the labels file name.
+%  \begin{verbatim}
+%    \documentclass{article}
+%    \usepackage{labels}
+%    \begin{document}
+%    \promptlabels
+%    \end{document}
+%  \end{verbatim}
+%
+% \subsection{Labels in the Main File}
+% The names and addresses can appear directly in the main
+% file, rather than using \verb|\labelfile| to include them.
+% The file format is to be exactly as described above. Especially,
+% follow the advice about blank lines, which delimit labels.
+% This example makes use of the |labels| environment.
+% \begin{verbatim}
+%   \documentclass{article}
+%   \usepackage{labels}
+%   \begin{document}
+%   \begin{labels}
+%   Me
+%   My address
+%   My City, State, Zipcode
+%
+%   My Brother
+%   His address
+%   His City, State, Zipcode
+%   \end{labels}
+%   \end{document}
+% \end{verbatim}
+%
+% \subsection{Control Sequences to Make Labels}
+% There are other ways of accessing the same system.
+% \begin{enumerate}
+% \item The control sequence called |\addresslabel[#1]{#2}| accepts for
+% optional argument |#1| \LaTeX{} controls, e.g., font size and style,
+% and for argument |#2| the rows of a |tabular| array of one column.
+%  \begin{verbatim}
+%    \documentclass{article}
+%    \usepackage{labels}
+%    \begin{document}
+%      \addresslabel[\small\sffamily]
+%      {Me \\my street \\ mytown \\ England}
+%    \end{document}
+%   \end{verbatim}
+%
+% \item Boxed labels use the special macro called
+% |\boxedaddresslabel[#1]{#2}|,
+% as follows. This produces a frame-box around the label itself, leaving
+% lots of white space around the frame. An optional argument |[#1]|
+% is provided for local setting of \LaTeX{} controls, for example,
+% |[\fboxsep=3pt]| will change the white space near the frame. The
+% boolean variable
+% |\LabelInfotrue| appears in the preamble in order to print out
+% additional information, especially the label dimensions and the
+% settings of certain variables.
+%  \begin{verbatim}
+%    \documentclass{article}
+%    \usepackage{labels}
+%    \LabelInfotrue
+%    \begin{document}
+%      \boxedaddresslabel[\fboxsep=3pt]
+%      {\textbf{Me} \\my street \\ mytown \\ England}
+%    \end{document}
+%   \end{verbatim}
+%
+% \item To \emph{duplicate} a label, there is a counter called
+% \verb|\numberoflabels| which you can set.
+% For example, to print a return address 21 times, use this
+% source:
+%  \begin{verbatim}
+%    \documentclass{article}
+%    \usepackage{labels}
+%    \numberoflabels=21
+%    \begin{document}
+%      \addresslabel{Me \\my street \\ mytown \\ England}
+%    \end{document}
+%   \end{verbatim}
+%
+% \item For more sophisticated users, there is a macro
+% \verb|\genericlabel| which you can call,
+% with an argument of whatever you want to appear on the label (e.g.,
+% for disk labels). Thus you could have
+%
+% \begin{tabular}{lp{1.0in}l}
+% \begin{minipage}{1.65in}
+%    \begin{verbatim}
+%    \genericlabel{%
+%    \begin{tabular}{|c|}
+%    \hline
+%    My Amazing Program\\
+%    \hline
+%    Disk 1 of 1\\
+%    \hline
+%    \emph{We aim to serve}\\
+%     \hline
+%    \end{tabular}
+%    }
+%    \end{verbatim}
+% \end{minipage}
+% &
+% \raggedright\sffamily
+%  to produce a label like this:
+% &
+% \begin{minipage}{1.4in}
+% \begin{verbatim}
+% |------------------|
+% |My Amazing Program|
+% |------------------|
+% |Disk 1 of 1       |
+% |------------------|
+% |We aim to serve   |
+% |------------------|
+% \end{verbatim}
+% \end{minipage}
+% \end{tabular}
+% \end{enumerate}
+% This feature has been used to print business cards with graphical
+% logo.
+%
+% \subsection{Wrapping Long Lines and Debugging}
+% Debugging of label files can be assisted by the internal error
+% messages which are emitted when a label box is too high or too wide
+% for the set parameters. This kind of error is unlikely to occur with
+% the standard controls and the \texttt{labels} environment, because by
+% default they use ragged right and wrap long lines.
+%
+% In all modes, you can opt for a grid around each label field by
+% setting a Boolean variable called |\LabelGridtrue|, e.g.,
+% \begin{verbatim}
+%    \documentclass{article}
+%    \usepackage{labels}
+%    \LabelGridtrue
+%    \numberoflabels=21
+%    \begin{document}
+%      \addresslabel{Me \\my street \\ mytown \\ England}
+%    \end{document}
+% \end{verbatim}
+% By default you get no grids. The grids are useful for judging the
+% `spillover' of addresses onto adjacent labels, caused by long lines.
+% See also |\boxedaddresslabel|, which draws a tighter box with more
+% white space around the label text. Both can be used at the same time.
+%

+% \section{The macros}
+% First of all, identify the package start, and specify that we
+% recognise the |newdimens| option.  The |\iflabel@traddimens| macro
+% will record whether we are using the tradition |labels| dimension
+% system or not.

+% These variables are provided to allow you to force a border on the left

+% The other variables adjust the gutter width at the top and bottom of a
+% page. They apply just to these two edges, and do not apply to a
+% particular label.  Different defaults are necessary if we are using
+% |newdimens|.
+% A LaserJetIII seems to ignore about 8mm on the edges. Xerox machines

+% We need to reset all the dimensions appropriately for a page of labels,

+%    \end{macrocode}
+% Now calculate the size of labels simply as a proportion of the page
+% size (if you haven't got that right, this won't work, will it?).
+% This macro is to be executed before the first label is made. In
+% environment |labels| and macro |\genericlabel| (see below) this
+% happens automatically. If you write your own label environment or
+% macro, then model it after one of the aforementioned.
+% 
+% We have two versions of this macro, depending on whether the
+% |newdimens| option has been set.
+%    \begin{macrocode}
+\iflabel@traddimens
+\def\@LabelSetup{%
+ \global\label@width\textwidth
+ \global\divide\label@width by\LabelCols

+ \global\divide\label@height by\LabelRows
+%    \end{macrocode}
+% The top margin of the paper is generally unused for
+% labels. \textsf{Avery} 5360
+% label sheets have a $1/4$-inch gutter on the top and bottom. However,
+% there are no left or right margin gutters. We adjust the top margin to
+% keep the labels from printing on the gutter.
+%    \begin{macrocode}
+ \global\topmargin=-1in\global\advance\topmargin by\TopBorder
+%    \end{macrocode}
+% It is not usually advisable to make the label printing go right to
+% the edge of the available area, so |\area@width| gives
+% the area that will actually be used for printing; the width is
+% cut down by |\LeftBorder| plus |\RightBorder|. These dimensions can be
+% set to zero if you have a design that uses the whole label.
+%    \begin{macrocode}
+ \global\area@width=\label@width
+ \global\advance\area@width by -\LeftBorder
+ \global\advance\area@width by -\RightBorder
+%    \end{macrocode}
+% If the labels are to be produced on a grid, for debugging, then the
+% usual setting of |\fbox| separator width and |\fbox| rule width must
+% be subtracted so that the label box doesn't crash into the grid.
+%    \begin{macrocode}
+ \ifLabelGrid%
+ \global\advance\area@width by-2\fboxsep
+ \global\advance\area@width by-2\fboxrule
+ \fi
+%    \end{macrocode}
+% The height of the label box will be |2\half@label|. However, this box
+% will definitely crash into the grid lines. Reduce the label
+% height to account for the rule and separator widths that will be added
+% automatically by the boxing routine later on.
+%    \begin{macrocode}
+ \ifLabelGrid
+ \global\advance\label@height by-2\fboxsep

+% Again, |\area@width| gives the area that will actually be used for
+% printing; the width is cut down by |\LeftLabelBorder| plus
+% |\RightLabelBorder|.  These dimensions can be set to zero if you
+% have a design that uses the whole label.  Similarly, |\area@height|
+% gives the height of the printing area, |\half@label| gives half of
+% the label height and |\half@area| gives half of the printable area
+% height.

+%
+% The real label-making macro appears below.
+% It assumes the actual text is in a box called \verb|\this@label|.
+% It is vital to make sure spaces are not included at the end of lines in
+% these macros, or all hell breaks loose. Internal checks are made for
+% box width and height, to report violations. The environments and
+% macros provided below always produce a ragged right box of fixed
+% width. Use |\genericlabel| to defeat the ragged right box and fixed
+% box width.
+%
+%    \begin{macrocode}
+\def\make@label{%
+ \ifnum\LabelTotal=0\vfill\eject\LabelTotal=\LabelRows\relax
+ \multiply\LabelTotal by \LabelCols\fi
+ \advance\LabelTotal by -1\relax
+ \ifLabelGrid
+  \let\boxing@type\framebox
+ \else
+  \let\boxing@type\makebox
+ \fi
+%    \end{macrocode}
+% The boxes made by the method below can overflow horizontally or
+% vertically. The code below emits an error message which pinpoints the
+% trouble and the degree of difficulty encountered. Most of the time
+% the text wrapping and ragged right controls fix the problem, but some
+% extra long lines can be troublesome. An essential part of this code is
+% to test the box for zero width, which will emit an empty label. If we
+% are doing it on purpose, then emit the label, otherwise discard it.
+%    \begin{macrocode}
+ \settowidth{\LabTmp}{\usebox{\this@label}}%
+ \ifdim\LabTmp=0cm\let\action=\relax\else\let\action=\BuildB@x\fi
+ %\TypeoutBlurb{Box Width}{\LabTmp}%
+ \advance\LabTmp by -\area@width
+ \ifdim\LabTmp>0cm\relax

+ \ifdim\LabTmp>0cm\relax
+ \LabTmp=2\LabTmp\PkgBlurb{Label too tall}{\LabTmp}\fi
+%    \end{macrocode}
+% Check for an empty box. Build the box provided it has some
+% dimension or else we are skipping labels on purpose. Otherwise, it's
+% empty and we discard it.
+%    \begin{macrocode}
+ \ifnum\skip@labels<\sk@pped\let\action=\BuildB@x\fi
+ \action
+}
+%    \end{macrocode}
+% Now build the box for the actual label. The box has minimum
+% height, which is set by using a vertical rule of zero width. At the
+% same time, set a minimum box width.
+% Set a position to half-way up a strut of the height of the label,
+% thus forcing text to be the correct height and vertically centered.
+% Apply box methods to adjust the white space left and right, using
+% horizontal rules of zero height.
+%    \begin{macrocode}
+\def\BuildB@x{%
+ \iflabel@traddimens
+ \boxing@type[\label@width][c]{%

+   \usebox{\this@label}%
+   \rule{\RightBorder}{0pt}%
+ }}%
+%    \end{macrocode}
+% We have a slightly different system when we are using the new
+% dimension system.  We vertically center the label in the printing
+% area and indent in by the value of |\LeftLabelBorder|.  We also mess
+% with the value of |\fboxsep| to make a framed box which doesn't
+% interfere with the placing of the label text.

+% To print out dimensions in more usual millimeters,

+% into millimeters. The common \TeX{} points are also printed.
+%    \begin{macrocode}

+ \PackageWarning{labels}{#1 by \the\@Milli mm (\the #2)}%
+}
+\def\TypeoutBlurb#1#2{\ToMilli{#2}%
+ \typeout{#1=\the\@Milli mm (\the #2)}%
+}
+%    \end{macrocode}
+%
+% \section{User macros}
+% The basic case is a generic macro |\genericlabel{#1}| which takes its
+% argument |#1| and puts it out on a label. No ragged right. No fixed
+% width. Very basic.
+%    \begin{macrocode}
+\newcommand{\genericlabel}[1]{%
+ \iffirst@label\LabelSetup\first@labelfalse\fi%
+ \savebox{\this@label}{#1}\sticky@label\@gobblecr}
+%    \end{macrocode}
+% The more useful macro |\addresslabel[#1]{#2}| is based upon a tabular
+% environment, therefore it accepts lines ending in \verb"\\". It is
+% supposed to reproduce what is made by the |labels| environment. Extra
+% space left and right is removed from the tabular environment and the
+% width is fixed at value |\area@width| (see above for a discussion of
+% this computed dimension) with ragged right edge. The optional argument
+% |[#1]| is provided in order to set local values of certain variables,
+% for example, |[\fboxrule=2pt]| could appear as the optional argument
+% in order to locally change box rule size, without affecting the grid
+% line size used for debugging.
+% The plan is to use the common denominator of 2.09 and 2e, so
+% first we define some double argument double-talk.
+%    \begin{macrocode}
+\long\def\L@dblarg#1{\@ifnextchar[{#1}{\L@xdblarg{#1}}}
+\long\def\L@xdblarg#1#2{#1[]{#2}}
+%    \end{macrocode}
+% Using \LaTeX{2e} extensions, the command |\addresslabel[#1]{#2}| could
+% be coded as |\newcommand{\addresslabel}[2][]{...}|.
+% In coding common to both 2.09 and 2e, the following works:
+%    \begin{macrocode}
+\long\def\addresslabel{\L@dblarg{\@addresslabel}}
+\long\def\@addresslabel[#1]#2{\genericlabel{#1%
+ \begin{tabular}{@{}p{\area@width}@{}}\raggedright #2\end{tabular}}}
+%    \end{macrocode}
+% The macro |\boxedaddresslabel[#1]{#2}| adds a framed box around the
+% address label defined above. The trouble here is in determining the
+% box width, which is reduced from its normal size by the widths of the
+% box rule and rule separator. The optional argument |[#1]| is the same
+% as for the previous macro, but here it performs a real service,
+% because it is often the case that box rule and box separator sizes
+% should be adjusted locally.
+%    \begin{macrocode}
+\long\def\boxedaddresslabel{\L@dblarg{\@boxedaddresslabel}}
+\long\def\@boxedaddresslabel[#1]#2{\genericlabel{#1%
+ \addr@width=\area@width\advance\addr@width by-2\fboxsep%
+ \advance\addr@width by-2\fboxrule\fbox{%
+  \begin{tabular}{@{}p{\addr@width}@{}}\raggedright #2\end{tabular}}}}
+%    \end{macrocode}
+% The environment |labels|, for verbatim labels, will be defined.
+%    \begin{macrocode}
+\long\def\labels
+ {\iffirst@label\LabelSetup\first@labelfalse\fi\start@@label}
+\def\endlabels{\end@@label}
+%    \end{macrocode}
+% The label contents are saved in a box called |\this@label|, formed as
+% a raggedright minipage of width |\area@width|. The trick is to make
+% the end of line character into a macro |^^M| which gets executed each
+% time it is encountered. By testing for blank lines, we can find the
+% end of a series of consecutive address lines and cause the macro to
+% terminate the label box definition, and possibly start another. The
+% usual action taken on intercept of an end of line character is to
+% insert |\newline|. It is only the case of a blank line that causes
+% us to end the current label. Here, swallow a pending \verb|^M|, to
+% avoid having a blank line at the start of each label. Extra blank
+% lines cause blank labels, which are thrown away when encountered,
+% later on.  A technical point: we cannot use \verb|\sbox|, as
+% otherwise \TeX\ gets confused, attempting to use \verb|\bgroup| as
+% the second argument to \verb|\sbox|, which is not what we want.
+%    \begin{macrocode}
+\def\start@@label{%
+ \begin{lrbox}{\this@label}%
+  \begin{minipage}{\area@width}\raggedright%
+  \catcode `\^^M =\active\@gobblecr%
+}
+\def\end@@label{%
+ \end{minipage}\end{lrbox}%
+ \sticky@label}
+%    \end{macrocode}
+%
+% The principal support macros needed to define the |labels| environment
+% will be defined below. These macros assume names and addresses appear
+% as consecutive lines separated by a blank line. If we are in the
+% middle of consecutive address lines, then just start a new line.
+%    \begin{macrocode}
+\def\start@newline{\mbox{}\expandafter\newline}%
+%    \end{macrocode}
+% If we have met a blank line, then finish the current label and start a
+% new label.
+%    \begin{macrocode}
+\def\new@label{\end@@label\start@@label}%
+%    \end{macrocode}
+% The macro |^^M| invokes either |\start@newline| or |\new@label|. To
+% define it, we use some hackery from Phil Taylor. Step one is to
+% activate a control sequence at end of line.
+% \begin{macrocode}
+\catcode `\^^M = \active%
+%    \end{macrocode}
+% The opaque definition required uses |futurelet| to selectively expand
+% a control sequence during a definition. The macro |^^M| is supposed to
+% replace carriage returns by |\newline|, or else end this label and
+% start a new one with |\new@label|. The idea is to define |^^M| to be a
+% control sequence |\nexttoken|, active only when |^^M| has been made an
+% active control sequence. Then the expansion of |^^M{#1}| will be
+% |\nexttoken|, provided the next line |#1| following the current one
+% has no characters (except carriage return at the end). Otherwise, we
+% must be at the start of a new cluster of label lines.
+%    \begin{macrocode}
+\def ^^M{\futurelet\nexttoken\isitapar}%
+\def\isitapar{\ifx^^M\nexttoken\let\action=\new@label\else%
+ \let\action\start@newline\fi\action}%
+%    \end{macrocode}
+% Definitions involving |^^M| are finished. Re-instate the original
+% catcode for carriage-return.
+%    \begin{macrocode}
+\catcode `\^^M = 5\relax%
+%    \end{macrocode}
+% The syntax of the |labels| environment can be shortened to a single
+% line, provided an input file name is known and the contents have been
+% prepared for use with the |labels| environment.
+%    \begin{macrocode}
+\def\labelfile#1{\begin{labels}\input#1\end{labels}}
+%    \end{macrocode}
+% In the interest of a general engine for label production, the program
+% can prompt for the file name at runtime. This kind of feature makes it
+% possible to run one batch file to create labels, regardless of the
+% source.
+%    \begin{macrocode}
+\def\promptlabels{\typein[\labelfilename]{What is the name of the
+ label file?}
+ \labelfile{\labelfilename}}
+%    \end{macrocode}
+% It is possible that a number of empty labels should be printed before
+% going on to print the next set of labels.
+% The |\skiplabels| macro takes an
+% integer argument of the number of empty labels to produce. An |x| is
+% printed on the terminal for each such empty label. For example:
+%  \begin{verbatim}
+%    \documentclass{article}
+%    \usepackage{labels}
+%    \begin{document}
+%    \numberoflabels=19
+%      \boxedaddresslabel{Me \\my street \\ mytown \\ England}
+%      \skiplabels{2}% Make 21 on first sheet
+%    \numberoflabels=16
+%      \boxedaddresslabel{You \\your street \\ yourtown \\ England}
+%    \end{document}
+%   \end{verbatim}
+%    \begin{macrocode}
+\newcount\sk@pped
+\def\skiplabels#1{\sk@pped=#1%
+ \savebox{\this@label}{\rule{0pt}{.5in}}%
+ \skip@labels=0\relax
+ \loop\ifnum\skip@labels<\sk@pped\make@label%
+ \advance\skip@labels by 1\relax\repeat}

+% \item (SPQR) v.10, June 1995. Checked and issued.
+% \item (GG) v.11, January 1998.
+%        New counter |\LabelTotal| and page eject when this counter is
+%        zero.
+%        Beta version April 1996, released January 1998.  Documented
+%        \LaTeX{}209 style file |olabels.sty|.
+% \item (JDG) v.12, January 2002.
+%        Introduced more natural dimension description system, which
+%        is activated by the `|newdimens|' package option.  This is only
+%        implemented for the \LaTeXe\ version.
+% \item (JDG) v.13, May 2003.
+%        Bug fix release: don't break with the color package (thanks
+%        to Dominique de Waleffe for reporting it)
+%       
+% \end{itemize}
+% The crucial macros which make the system bearable for mailing lists
+% by redefining end of line came from Phil Taylor; apologies
+% to him for using them in a \LaTeX\ style file!
