+This small LaTex package provides the rendering of American style Karnaugh maps
+as found in many American text books on Digital Design. There are four files:
+
+README      - this file
+askmaps.sty - the package file
+askmaps.tex - the documention with examples
+askmaps.pdf - PDF version of the documentation
+
+The Karnaugh maps are rendered with picture commands; only the pict2e package
+is loaded.
+
+Current version is 0.1. At this point, only 2-5 variable Karnaugh maps
+are supported. People familiar with the Karnaugh package should have
+no problem in using the macros in this package.
+
+Suggestions and bug reports are welcome at J.E.J.opdenBrouw@hhs.nl
+
+Happy TeX-ing!

+\section{Abstract}
+\label{sec:abstract}
+This package generates configurable American style Karnaugh maps for
+2, 3, 4 and 5 variables as can be found in numerous books on digital design.
+Note that there are many ways to draw correct Karnaugh
+maps\footnote{E.g., a four-variable Karnaugh map can be drawn in 384 different
+and correct ways} and this packages creates only one version.
+
+There are more packages and examples that produce Karnaugh maps. A highly
+recommendable package is written by Andreas W. Wieland\footnote{See
+\url{http://www.ctan.org/tex-archive/macros/latex/contrib/karnaugh}}.
+However, this package creates maps that are frequently found in dutch
+textbooks\footnote{E.g. Digitale Techniek, A.P. Thijssen}
+but not in American textbooks.
+
+\section{Overview}
+\label{sec:overview}
+After \cmdinvoke{usepackage}{askmaps}, four new commands are loaded
+to draw Karnaugh maps using the picture environment:
+\begin{table}[H]
+\begin{tabular}{p{2cm}p{10cm}}
+\cs{askmapii}  & draws a two-variable Karnaugh map \\ 
+\cs{askmapiii} & draws a three-variable Karnaugh map \\ 
+\cs{askmapiv} & draws a four-variable Karnaugh map \\ 
+\cs{askmapv} & draws a five-variable Karnaugh map \\
+\end{tabular} 
+\end{table}
+
+These commands have five parameters which have the same meaning for each
+commands. This will be explained in section \ref{sec:outline}. As can be seen
+later on, much of the parameters can include typesetting commands such as
+coloring and math notation.
+
+The new dimension \cs{askmapunitlength} is available and specifies
+the length of the squares. It defaults to 1 cm (about 0.4 in) which is a good
+value for 12 pt font size.
+
+The global definitions \cs{askmapsversion} and \cs{askmapsdate} will render
+to the current version and date respectively.
+
+The command \cs{askmap} provides drop-in replacement for the \cs{karnaughmap}
+command available in the \Package{kvdocs} package (although it is not really a
+package) and internally calls one of the four
+commands, but there are some drawbacks on using this command.
+
+\newpage
+\section{Outline}
+\label{sec:outline}
+All four functions take the form
+\cs{askmap<romannumber>\{\#1\}\{\#2\}\{\#3\}\{\#4\}\{\#5\}}
+where \texttt{<romannumber>} is one of \texttt{ii}, \texttt{iii}, \texttt{iv}
+or \texttt{v} and the parameters \texttt{\#1} to \texttt{\#5} have the
+following meaning:
+
+\begin{itemize}
+	\itemsep0pt
+	%\labelsep0pt
+	\item[\texttt{\#1}] is the function output variable.
+	\item[\texttt{\#2}] is a list of function input variables.
+	\item[\texttt{\#3}] contains a list op options, see table below.
+	\item[\texttt{\#4}] is a list of function values.
+	\item[\texttt{\#5}] can be used to display user defined picture commands.
+\end{itemize}
+
+If a parameter contains fewer elements than needed, you will get empty spaces
+in the Karnaugh map. If a parameter contains more elements than needed, all
+elements in excess are not printed. In both situations, you will not be
+notified.\newline
+
+The third parameter contains a list of options as explained below.
+\begin{itemize}
+    \itemsep0pt
+    \item[\texttt{i}] index numbers are printed in the lower left corner of
+                      each square.
+    \item[\texttt{I}] no index numbers are printed (default).
+    \item[\texttt{f}] function output variable is printed at the upper right
+                      corner of the Karnaugh map together with a small line
+                      extending from the square to the function name (default).
+    \item[\texttt{F}] no function output variable is printed.
+    \item[\texttt{b}] bit combinations of the function input variables are
+                      printed on top of the columns and at the right of the the
+                      rows (default).
+    \item[\texttt{B}] bit combinations are not printed.
+    \item[\texttt{c}] shortcut for \texttt{ifb}.
+    \item[\texttt{C}] shortcut for \texttt{IFB}.
+\end{itemize}
+
+Options are evaluated from left to right, so a combination of \texttt{iI} will
+yield in no index numbers being printed. Please note that macros are not
+expanded to a list of tokens but to one token.\newline
+
+If you look at American style Karnaugh maps, you will see that the function
+output variable usually isn't printed with the map, but is printed below the
+map (if it is printed at all). This behavior can be simulated by using the
+\texttt{F} option, in which case the first parameter (the function output
+variable) may be left unused.
+
+
+\section{Use}
+\label{sec:use}
+Let's say we have the following truth table for a function S with two variables
+a and b and the function values 1, 0, 1 and 1 respectively.
+
+\begin{table}[H]
+\centering
+\caption{Truth table}
+\begin{tabular}{cc|c}
+\hline 
+a & b & S \\ \hline 
+0 & 0 & 1 \\ 
+0 & 1 & 0 \\ 
+1 & 0 & 1 \\ 
+1 & 1 & 1 \\ 
+\hline 
+\end{tabular} 
+\end{table}
+
+Using the command
+\begin{verbatim}
+  \askmapii{S}{ab}{i}{1011}{}
+\end{verbatim}
+will produce the two-variable Karnaugh map as presented in
+figure~\ref{fig:askmapii}.
+\begin{figure}[h]
+\centering
+\askmapunitlength=0.88cm
+\askmapii{S}{ab}{i}{1011}{}%
+\caption{Karnaughmap for two variables}
+\label{fig:askmapii}
+\end{figure}
+
+As you can see, the function output variable is printed top right of the
+Karnaugh map, with a small line from the variable to the top right square.
+The most significant function input variable is printed on the top left just
+above the small line extending from the top left square. The least significant
+function input variable is printed just below that line. The bit combinations
+for the most significant function input variable is printed on top of the
+columns, the bit combinations of the least significant function input variable
+is printed on the left of the rows. You can see how the function values are
+placed in the squares by observing the small index numbers in the lower left
+corners of the squares.
+\medskip
+
+The command 
+\begin{verbatim}
+  \askmapiii{S}{abc}{}{10110110}{}
+\end{verbatim}
+will produce a three-variable Karnaugh map as presented in
+figure~\ref{fig:askmapiii}. In this case, the index numbers are not printed.
+
+\begin{figure}[H]
+\centering
+\askmapunitlength=0.88cm
+\askmapiii{S}{abc}{}{10110110}{}%
+\caption{Karnaugh map for three variables}
+\label{fig:askmapiii}
+\end{figure}
+
+Let's draw a Karnaugh map for a logic function with four inputs and one output.
+The output will become logic 1 if three or four inputs are logic 1, otherwise
+the output is logic 0. (Of course you can set up a truth table first; this is
+left as an exercise to the reader).
+The command 
+\begin{verbatim}
+  \askmapiv{S}{abcd}{}{0000000100010111}{}
+\end{verbatim}
+will produce a four-variable Karnaugh map for the given logic function and is
+presented in figure~\ref{fig:askmapiv}.
+
+\begin{figure}[H]
+\centering
+\askmapunitlength=0.88cm
+  \askmapiv{S}{abdc}{}{0000000100010111}{}
+\caption{Karnaugh map for four variables}
+\label{fig:askmapiv}
+\end{figure}
+
+Using the command
+\begin{verbatim}
+  \askmapv{S}{abcde}{}{00101101010010111011110011101011}{}
+\end{verbatim}
+will produce a five-variable Karnaugh map as shown in figure \ref{fig:askmapv}.
+
+\begin{figure}[H]
+\centering
+\askmapunitlength=0.88cm
+  \askmapv{S}{abcde}{}{00101101010010111011110011101011}{}
+\caption{Karnaugh map for five variables}
+\label{fig:askmapv}
+\end{figure}
+
+Of course you can do a lot more with the parameters of the commands. You
+can use inline math to produce sophisticated variable names, you can
+use coloring for the function values. However, please note that the second
+and fourth parameter act as a list of tokens, so you have to use braces to
+separate the tokens in the lists if they consists of multiple characters.
+A list of tokens such as
+\begin{verbatim}
+  {abcd}
+\end{verbatim}
+will yield a, b, c and d as separate tokens, but
+\begin{verbatim}
+  {$m_{0}$$m_{1}$$m_{0}$$m_{1}$}
+\end{verbatim}
+will not work. You have to write
+\begin{verbatim}
+  {{$m_{0}$}{$m_{1}$}{$m_{0}$}{$m_{1}$}}
+\end{verbatim}
+
+The fifth parameter can be used to supply user created picture commands
+such as dashed rectangles of ovals to emphasize the simplifications
+in the function. Note that the origin
+of the picture (0,0) is at the lower left corner of the lower left square.
+Section \ref{sec:examples} shows some examples.
+\bigskip
+
+The size of the indexes is scriptsize, the size of the bit combinations
+on the edges of the Karnaugh maps is footnotesize. All other text is
+in normalsize. Note that there are no commands to change the font sizes
+in the Karnaugh diagrams.
+
+
+The command \cs{askmap} provides a drop-in replacement for the command
+\cs{karnaughmap} from the Karnaugh package. The command
+\begin{verbatim}
+  \askmap{4}{F}{abcd}{0100101010100011}{}
+\end{verbatim}
+produces the Karnaugh map in figure \ref{fig:askmap}.
+\begin{figure}[H]
+\centering
+\askmapunitlength=0.88cm
+  \askmap{4}{F}{abcd}{0100101010100011}{}
+\caption{Karnaugh map using drop-in replacement}
+\label{fig:askmap}
+\end{figure}
+
+Only Karnaugh maps of two to five variables are supported, any other number
+will trigger a warning. Please note that the \cs{kvindex}, \cs{kvindexsize}
+and \cs{kvcontentsize} commands are not supported.

+\section{The source code}
+\label{sec:sourcecode}
+The source code is pretty straight forward. It uses a lot of picture primitives
+for drawing the maps. The package uses three macros for processing
+variable-length parameters, which were completely reused from the karnaugh
+package.

+  
+%% This package provides 2, 3, 4 and 5 variable Karnaugh maps that can
+%% be found in numerous american text books on digital design. Note
+%% that it is possible to draw many different K-maps that are all
+%% legitimate as long as a square (minterm) differs only in one
+%% literal with its adjacent squares.
+%% This package draws K-maps where the most significant input variables
+%% are placed on top of the columns and the least significant variables
+%% are placed left of the rows. Such K-maps can be found in the text books:
+%%  Design of Logic Systems, 2nd, Lewin & Protheroe
