+\maketitle
+\section{Introduction}
+Dice fonts are already available in \textsc{metafont} format.
+(I should know, I wrote one myself: \texttt{dice3d.mf}.)
+For some applications it seems preferable, however, to have the fonts
+in scalable form. The package \texttt{epsdice} fills this gap.
+
+\texttt{epsdice.sty} provides a single command,
+\verb+\epsdice{#1}+, taking one mandatory argument, an integer from 1 to 6,
+and recognising one optional argument, namely \verb+[black]+
+for a black die with white dots.\footnote{Thanks to Chrisoph Zurnieden for
+suggesting the extension with reversed colors, and for adjusting the drawings
+to this purpose.} The default behavior (i.e., with \emph{no} optional argument
+or with \emph{any optional argument other} than \verb+[black]+) results in
+a white die with black dots.
+
+The mandatory argument may also be the value of a counter. Thus
+automatic representation of (generated or input) data is possible as well.
+Of course, values outside the range 1--6 will not be represented as die faces.
+
+Depending on the value of the argument, \verb+\epsdice+ includes the
+appropriately clipped region from a file containing simple drawings
+of die faces. The drawings scale with the current font because the
+height of the included graphics file is set in terms of `ex' units.
+%
+\section{Requirements and limitations}
+\texttt{epsdice} relies on the \texttt{graphicx} package to include
+the drawings.
+It also uses the \texttt{ifthen} package to validate the arguments
+(error checking).
+
+The package has been tested with two widely used package drivers
+for \texttt{graphicx}: \verb+[dvips]+ and \verb+[pdftex]+. By
+default, the command \verb+\epsdice+ includes
+\texttt{epsdice.eps} under \LaTeXe, and \texttt{epsdice.pdf}
+under pdf\LaTeX, respectively\footnote{Many thanks to Rolf
+Niepraschk for his help with the latter!}
+(unless your \texttt{graphics.cfg} file specifies non-standard
+settings).
+
+Clipping is supported only in pdf\TeX\ versions
+$\ge 0.14$. You will also need an up-to-date version of
+\texttt{pdftex.def}: Clipping is not supported in versions
+\texttt{v0.03c} \texttt{[2000/09/04]} or earlier.
+If your pdf\TeX\ is up-to-date but
+you still receive error messages about clipping not being
+supported, get the latest \texttt{pdftex.def}
+here: \\[.5ex]
+\verb+http://www.tug.org/applications/pdftex/pdftex.def+
+\\[.5ex]
+I tested the package successfully with pdf\TeX\ 0.14e
+and \texttt{pdftex.def} v0.03f \texttt{[2000/11/10]}.
+%
+\section{Configuring this package}
+To finish the installation of the package,
+simply move the following files somewhere in your ``local texmf tree'':
+\begin{verbatim}
+ epsdice.sty, epsdice.cfg, dice.eps, dice.pdf
+\end{verbatim}
+e.g.\ to a new subdirectory
+\verb+/tex/latex/epsdice/+. Refresh the
+\TeX-system's file name database, and that's it, you're all set!
+The remainder of this section applies only if you want to change
+the default settings.
+
+The command \verb+\epsdice+ works by including an
+external file, so this file must be found by \LaTeXe. The package comes with
+a configuration file \texttt{epsdice.cfg} containing the file name in the
+variable \verb+\dicefile+. By default, this variable points to the file
+\verb+dice.{eps|pdf}+ (without file name extension). If you don't like my
+drawings and would like to ``roll your own'', a look at section~\ref{pscode}
+may give some hints.
+It contains the same PostScript code as \texttt{dice.eps},
+with some comments about what's going on. Conversion to \textsc{pdf}
+format has been accomplished with \texttt{epstopdf} (using
+GhostScript), see pdf\TeX's web page.
+
+If you intend to keep the external file with the dice drawings in a
+different place or if you want to use your own version you have to
+edit the configuration file \texttt{epsdice.cfg} accordingly,
+by adding the path to the file name, or by changing the file name in the
+variable \verb+\dicefile+.
+If a configuration file does not exist, the external file
+is assumed to be located in the present working directory.
+%
+\section{Examples}
+Die faces in an 11pt environment: The pictures fit into the surrounding
+text, as in \epsdice{1} \epsdice[black]{2} \epsdice[black]{3}
+\epsdice[red]{4} \epsdice[black]{5} \epsdice[white]{6}. The code used to set
+these die faces was:
+\begin{verbatim}
+\epsdice{1} \epsdice[black]{2} \epsdice[black]{3}
+\epsdice[red]{4} \epsdice[black]{5} \epsdice[white]{6}
+\end{verbatim}
+The only effective option to the command \verb+\epsdice+ is \verb+[black]+.
+Anything else results in the default behavior with white background.
+
+\medskip
+{\Large
+Here is some \verb+\Large+ text. The die pictures scale accordingly:%
+\footnote{\ldots as they do in footnotes, \epsdice{\value{footnote}},
+like this.} \epsdice{3} \epsdice[black]{5}. See?}
+
+\medskip
+Finally, note that the package works with
+standard counters, too: Here's the result of \verb+\epsdice{\value{section}}+
+\epsdice{\value{section}}.
+%
+\section{Drawing dice in PostScript}
+\label{pscode}
+Something as simple as a ``square with dots
+on it'' is rather straightforward to draw in PostScript. The first line
+\begin{flushleft}
+\verb+%!PS-Adobe-2.0 EPSF-1.2+
+\end{flushleft}
+is just a standard header. Next comes the bounding box: Each face measures
+$32\times 32$~pt, centered in a $43\times43$~pt box. For six faces in a row,
+this gives a bounding box of $258\times43$~pt. We have two rows of dice,
+the lower row containing the white dice with black dots, the upper one the
+black dice with white dots. So the total bounding box is $258\times86$~pt.
+The background color will be stored in the variable $bw=0$ or 1.
+\begin{verbatim}
+%%BoundingBox: 0 0 258 86
+\end{verbatim}
+The \verb+/frame+ macro defines a simple box with rounded corners. It takes
+one argument, the face index $n$, and calculates a corresponding $x$-offset:
+$x_{\mathrm{off}}=43 (n-1)$. The point $(x_{\mathrm{off}},y_{\mathrm{off}})$
+then becomes the origin of the coordinate system for this particular face.
+This macro uses the variable $bw$ to calculate the vertical offset
+$y_{\mathrm{off}}=43 bw$.
+The frame consists of straight lines separated by 5~pt from the outer margin,
+and of four quarter circles with radius $r$ ($r=5$~pt for black on white and
+$r=6$~pt for white on black) centered at $(10,10),\,(32,10),\,(10,32)$, and $(32,32)$.
+\begin{verbatim}
+/frame {
+ /n exch def % take n off the stack, store it
+ /xoffset n 1 sub 43 mul def % xoffset = 43*(n-1)
+ gsave % save the graphics state
+ newpath % start a new path
+ xoffset yoffset translate % move origin to (xoffset,yoffset)
+ 32 5 bw sub moveto % go to (32,5) or (32,4) in this system
+ 32 10 r -90 0 arc % SE quarter circle around (32,10)
+ 37 bw add 32 lineto % right line
+ 32 32 r 0 90 arc % NE quarter circle around (32,32)
+ 10 37 bw add lineto % top line
+ 10 32 r 90 180 arc % NW quarter circle around (10,32)
+ 5 bw add 10 lineto % left line
+ 10 10 r 180 270 arc % SW quarter circle around (10,10)
+ closepath % bottom line (closes the path)
+ bw 0 eq { stroke } % either paint (lower row, bw=0)
+ { fill } ifelse % or fill (upper row, bw=1) the path
+ grestore % restore graphics state
+} def
+\end{verbatim}
+The dot positions are labelled within a face by $(x,y)$-coordinates
+running from $(1,1)$
+for bottom left to $(3,3)$ for top right. The dot itself is
+a filled circle with radius $3.5$~pt. Change the dots' positions
+within the frame, or their radius, as you like. The \verb+/dot+ macro
+takes three arguments off the stack: (i) the face index, to determine
+the $x$-offset, (ii) the $x$-coordinate (1, 2, or 3) on the face, and
+(iii) the $y$-coordinate (1, 2, or 3) on the face.
+\begin{verbatim}
+/dot {
+ /y exch def % take y-coordinate off the stack
+ /x exch def % take x-coordinate off the stack
+ /n exch def % take face index n off the stack
+ /xoffset n 1 sub 43 mul def % xoffset = 43*(n-1)
+ gsave % save the graphics state
+ newpath % start a new path
+ xoffset yoffset translate % move origin to (xoffset,yoffset)
+ x 8 mul 5 add % the dot's x-position: 8*x+5
+ y 8 mul 5 add % the dot's y-position: 8*y+5
+ 3.5 0 360 arc % a circle with radius 3.5 pt
+ closepath % close the circle
+ bw setgray % set the appropriate color
+ fill % fill the circle
+ grestore % restore graphics state
+} def
+\end{verbatim}
+Now choose a linewidth (2~pt)
+\begin{verbatim}
+2 setlinewidth
+\end{verbatim}
+and loop over the background color (and hence the rows) from 0 to 1.
+The color counter is stored in $bw$ and used
+to determine $y_{\mathrm{off}}$ as well as the radius of the circles,
+$r=5+bw$~pt.
+\begin{verbatim}
+0 1 1 { % set up loop from 0 to 1
+ /bw exch def % store loop index in bw
+ /yoffset bw 43 mul def % yoffset = 43*bw
+ /r 5 bw add def % radius r = 5+bw
+ 0 setgray % set color to black for all frames
+\end{verbatim}
+All we have to do now is draw the six faces
+\begin{verbatim}
+ 1 1 6 { frame } for % call /frame macro for n=1..6
+\end{verbatim}
+and fill in the appropriate dots.
+The bottom left and top right dots appear on faces 2, 3, 4, 5, and 6.
+Thus there is an outer loop from 2 to 6 in steps of 1. For each of these
+face indices, we call the dot macro with $(x,y)$-argument equal to
+$(1,1)$ and $(3,3)$. This can be achieved with an inner loop running
+from 1 to 3 in steps of 2. Because the $x$- and $y$-coordinates coincide
+for these particular points, we obtain them by duplicating the inner
+loop index. The \verb+/dot+ macro gobbles not only the $x$- and
+$y$-coordinates but the face index as well. In order to draw \emph{two}
+dots on the same face, we thus have to duplicate the outer loop index, too.
+\begin{verbatim}
+ 2 1 6 { % start loop 2 to 6 in steps of 1
+ dup % duplicate index (two dots on each face)
+ 1 2 3 { % start loop 1 to 3 in steps of 2
+ dup % duplicate loop index -> 1 1 and 3 3
+ dot % call /dot macro, using three arguments
+ } for % inner loop (dot positions)
+ } for % outer loop (face index)
+\end{verbatim}
+The center dot appears on faces 1, 3, and 5. We get it in a simple loop
+from 1 to 5 in steps of 2, calling the \verb+/dot+ macro for each index
+together with the coordinate set $(2,2)$ corresponding to the center.
+\begin{verbatim}
+ 1 2 5 { 2 2 dot } for % (2,2) dot on 1, 3, 5
+\end{verbatim}
+The top left and the bottom right dots appear on faces 4, 5, and 6. Again,
+in order to draw \emph{two} dots on each face, we have to duplicate the
+loop index, i.e., the face index:
+\begin{verbatim}
+ 4 1 6 { % start loop 4 to 6 in steps of 1
+ dup % duplicate index (two dots on each face)
+ 1 3 dot % call /dot macro for (1,3) dot on this face
+ 3 1 dot % call /dot macro for (3,1) dot on this face
+ } for % loop over face index
+\end{verbatim}
+Finally, on face 6 we have two dots in positions $(1,2)$ and $(3,2)$. We can
+use a loop, but then we have to swap the loop index, i.e., the dot's
+$x$-coordinate, with the (constant) face index 6 inside the loop.
+\begin{verbatim}
+ 1 2 3 { % start loop 1 to 3 in steps of 2
+ 6 exch % swap loop index and constant face index
+ 2 % push constant y-coordinate on stack
+ dot % call /dot macro for (x,2) dot on face 6
+ } for % loop over x-coordinates 1 and 3
+\end{verbatim}
+And this closes the loop over background colors:
+\begin{verbatim}
+} for % loop over bw 0 and 1
+\end{verbatim}
+That's it!
+\begin{verbatim}
+%%EOF
+\end{verbatim}
+\section{Errors}
+Of course it doesn't make sense to ask for die faces with arguments
+other than 1, 2, 3, 4, 5, or 6. The package generates error
+messages and simply prints the offending argument in the \TeX\ output.
+%
+% This generates `benign' errors: \epsdice{99} and \epsdice{-3}.
+% The following is more serious, generating two different errors:
+% \epsdice{epsfoo}. Nevertheless, output continues with a fall-back
+% solution.
