% \begin{abstract}
%   This package draws karnaugh maps with 2, 3, 4, 5, and 6 variables.
%   It also contains commands for filling the karnaugh map with terms semi-automatically or manually.
%   Last but not least it contains commands for drawing implicants on top of the map.
%   Below is an example of a two variable karnaugh map of $X_0 \oplus X_1$.

%    The |karnaugh-map| environment is the base for this package, and everything related to this package happens inside an instances of this environment.
%
%    \textbf{Usage:}
%
%    \begin{tabularx}{\textwidth}{l X}
%      \small{|\begin{karnaugh-map}|} & \\
%      \small{\parg{options}}     & \small{See section \ref{sec:usage:options}. Default: ''''} \\
%      \small{\meta{*}}           & \small{One asterisk for black and white implicants, non for colorized implicants} \\
%      \small{\oarg{X size}}      & \small{Number of X-axis cells. Default: ''4''} \\
%      \small{\oarg{Y size}}      & \small{Number of Y-axis cells. Default: ''4''} \\
%      \small{\oarg{Z size}}      & \small{Number of X$\times$Y submaps. Default: ''1''} \\
%      \small{\oarg{label A}}\footnotemark     & \small{Label for the variable one. Default: ''$X_0$''} \\

%      \small{\oarg{label D}}     & \small{Label for the variable four. Default: ''$X_3$''} \\
%      \small{\oarg{label E}}     & \small{Label for the variable five. Default: ''$X_4$''} \\
%      \small{\oarg{label F}}     & \small{Label for the variable six. Default: ''$X_5$''} \\
%    \end{tabularx}
%
%     \footnotetext{The arguments \oarg{label A}, \oarg{label B}, and \oarg{label C} are currently backward compatible with \oarg{X label}, \oarg{Y label}, and \oarg{Z label} in version v1's definition of the |karnaugh-map| environment. This works through a heuristic method. However the v1 definition is now deprecated and this backward compatibility may disappear in a later version.}
%
%    \textbf{Example:}
%
%    Four variable karnaugh map, colorized, with X label $X_1X_0$, and Y label $X_3X_2$.
%    \begin{verbatim}
%\begin{karnaugh-map}

% \begin{macro}{\implicantedge}
%    The |\implicantedge| command draws quadratic implicants with the middle of the implicant facing the edge of a submap either horizontally or vertically. The function is able to draw the same implicant on one or multiple submaps. However if the implicant shall be drawn on multiple submaps, \marg{northwest part - northwest cell}, \marg{northwest part - southeast cell}, \marg{southeast part - northwest cell}, \marg{southeast part - southeast cell} must be specified as if the implicant was to be drawn on the 0:th submap. When turned on, colorization is done automatically, following a global sequence of available colors.
%
%    \textbf{Usage:}
%
%    \begin{tabularx}{\textwidth}{l X}
%      \small{|\implicantedge|}                       & \\
%      \small{\marg{northwest part - northwest cell}} & \small{The most northwest cell in the northwest part of the implicant} \\
%      \small{\marg{northwest part - southeast cell}} & \small{The most southeast cell in the northwest part of the implicant} \\
%      \small{\marg{southeast part - northwest cell}} & \small{The most northwest cell in the southeast part of the implicant} \\
%      \small{\marg{southeast part - southeast cell}} & \small{The most southeast cell in the southeast part of the implicant} \\
%      \small{\oarg{submaps}}                         & \small{Comma separated list of submaps the implicant should be drawn on. Default: ''0''} \\

% \subsection*{Resizing}
% The karnaugh maps produced with this package have a prespecified size which can not be changed. However you can resize the karnaugh map to your desired size. Resizing can be done using the |\resizebox| command from the graphicx package. Scaling the karnaugh map to fill the column width while preserving the aspect ratio can be done as follows.
% \begin{verbatim}
%\resizebox{\columnwidth}{!}{%
%  \begin{karnaugh-map}
%  \end{karnaugh-map}%
%}
% \end{verbatim}
%
% \subsection*{Comma separated lists}
% Anywhere in this package where a comma separated list is used data should only be comma separated. Therefore a comma and space separated list will for example \textit{not} work properly.
%
% An example of errorious usage related to the \small{\marg{cells}} parameter in the terms related commands can result in multiple zeros, ones and other terms overlapping in the same cell in the outputted karnaugh map.
