\typeout{}
%%
%% Change History:
%% 1.0: 22 December 2017: Original Version ported from kvmacros.tex
%% 1.1: 10 January 2018: new style for the map outer box. Support for
%% options in the identifiers and values lists. New vertical mode.
%% New keys to enable indices and disable bars. Macro file renamed
%% to proper tikz library file name.
%% 1.2: 19 March 2018: stop using \pgftransformshift, new kmindexpos
%% (kmindexposx and kmindexposy) to control index position, cell
%% typesetting order switched (first content then index), parameter
%% names changed to include ``km'' letters, new binary index mode
%%
%% Setting up some TikZ parameters for Karnaugh Maps
%%
\tikzset{
  karnaugh/.style={

\kmunitlength=8mm
%%
%% First, we have to introduce some counters:
%%
%% \kmrecursiondepth is used to control the recursion of the
%% \karnaughmakemap macro.
%%
\newcount\kmrecursiondepth
%%
%% The \kmindexcounter is needed for the indices in the fields of the
%% diagrams. 
%%
\newcount\kmindexcounter
%% 
%% \kmxsize and \kmysize store the dimensions of an entire diagram.
%%
\newcount\kmxsize
\newcount\kmysize
%%
%% Some counters are necessary to compute the bars for the variable
%% identifiers:
%%
\newcount\kmvarno
\newcount\kmxvarno
\newcount\kmyvarno
\newcount\kmbarstart
\newcount\kmbarlength
\newcount\kmbarnum
\newcount\kmbarmove
\newcount\kmtemppos

%% use (ok, not really, but it might be useful).

%% process the variable-length parameters in \karnaughmap:
