+% This file provides a high-level automatic export feature for tikz pictures.
+% It allows to export EACH SINGLE FIGURE into a separate PDF.
+%
+% The simplest way is to use 
+%
+% \tikzexternalize{myarticle}
+%
+% it simply converts every figure using the write18 method. If that is not possible,
+% you need to reconfigure \tikzexternalize: it can generate a list of figure file names 
+% and you need to generate these figures manually (or with a script).
+%
+% It replaces \tikzpicture/ \endtikzpicture and \tikz and invokes \beginpgfgraphicnamed ... \endpgfgraphicnamed
+% commands if necessary.
+
+% source generic implementation:
+\input tikzexternalshared.code.tex
+
+\def\tikzexternal@TEXDIALECT@begpicture{\begin{tikzpicture}}
+\def\tikzexternal@TEXDIALECT@endpicture{\end{tikzpicture}}%
+
+% this latex specific this assumes it starts at the beginning of an
+% environment. The environment is named
+% '\tikzexternal@laTeX@collect@until@end@tikzpicturetikzpicturestring'.
+%
+% Everything up to \end{<name>} will be collected and passed as
+% argument to the macro '#1'.
+%
+% This does also work if <name> is NOT tikzpicture!

+	\begingroup
+	\t@tikzexternal@tmpa={}%
+	\tikzexternal@laTeX@collect@until@end@tikzpicture{#1}%

+
+% Loop until we find '\end{tikzpicture}'.  We have to make sure that
+% even strings like '#1' are allowed inside of the collected argument.
