+% TODO for auto xrefs:
+% 1. check the already identified labels, preferrably using
+% /pdflinks/show labels=true
+% and the image externalization debug mode (see pgfmanual-en-main.tex)
+% (to strip almost all images away)
+%
+% 2. Insert '\declareandlabel' in the document whenever something has been
+% defined in the text, so it should get a pdf anchor (see
+% pgfmanual.pdflinks.code.tex )
+%
+% 2.1 perhaps insert \pgfmanualpdflabel{<label>}{} where needed.
+%
+% 3. Verify that the |...| commands occuring in situations where catcodes can't
+% be changed (footnotes or macro arguments) work as expected.
+%
+% 4. Consider telling the pretty printer that several control sequences
+% have arguments which are options (see below for the predefined list).
+% This may apply to \pgfpageslogicalpageoptions or so.
+%
+% 5. @Christian: consider extensions of the parser such that it identifies path commands (at least partially)

+% This file provides an interface to the
+% pgfmanual.prettyprint.code.tex thing -- it allows to
+% *generate pdf crossrefs inside of codeexamples automatically*
+% without any user input.
+%
+% Thus, you write
+% \begin{codeexample}[]
+% \begin{tikzpicture}[options]
+% \end{tikzpicture}
+% \end{codeexample}
+% and pdf cross references to the definitions of 'tikzpicture'
+% and any options will be generated automatically.
+%
+% Furthermore, pdf cross references will be generated for everything
+% within vertical bars, |....|.
+%
+%
+%
+%
+%
+% The only necessary thing is that \pgfmanualpdflabel has been called
+% for every (fully qualified) key, control sequence, environment or
+% whatever.

+%
+% #1: is the NUMBER of arguments to collect.
+% #2: is TeX code which shall be invoked after
+% \pgfmanualprettyprinterhandlecollectedargs has been invoked (see
+% below).
+%
+% PRECONDITION:
+% there is a large token list following
+% \pgfmanualprettyprintercollectargcount with balanced braces. The braces
+% have \catcode 12.
+% POSTCONDITION:
+% 1. the arguments will be collected as
+% '<result> := {<first arg>}{<second arg>}',
+% 2.1 the macro \pgfmanualprettyprinternumcollectedargs will contain
+% the *actual* number of *completely* collected arguments,
+% 2.2 the if \ifpgfmanualprettyprinterarghasunmatchedbraces will be
+% set to \c true if the last found argument had an unmatched brace,
+% 3. then, \pgfmanualprettyprinterhandlecollectedargs{<result>} will be
+% invoked. Just define \pgfmanualprettyprinterhandlecollectedargs
+% properly.
+% Afterwards, #2 will be invoked to recover from the argument
+% collection.
+%
+%
+% Example:
+% \pgfmanualprettyprintercollectargcount{2}{\donnextstep}
+% {_12 first argument }_12 {_12 second argument }_12 next tokens%
+%
+% will result in the expansion
+% \pgfmanualprettyprinterhandlecollectedargs{{_1 first argument }_2 {_1 second argument }_2 }
+% \donnextstep
+% next tokens
+%
+%
+%
+% ATTENTION:
+% \pgfmanualprettyprinterhandlecollectedargs will be invoked with a SINGLE
+% argument. The argument as such will contain extra braces, one pair
+% of braces for each of the #1 arguments. These braces will have
+% catcode 1 and 2, i.e. they can *really* be used in TeX. Thus, the
+% finish routine will be invoked with
+% \pgfmanualprettyprinterhandlecollectedargs{{<arg>}}
+% for one argument and with
+% \pgfmanualprettyprinterhandlecollectedargs{{<first arg>}{<second arg>}}
+% for two and more arguments. Note the extra set of braces for one
+% arg.
+% It might happen that not all arguments have been found if
+% end-of-input occured before. The
+% \pgfmanualprettyprinterhandlecollectedargs routine has to check
+% this using the macro \pgfmanualprettyprinternumcollectedargs which
+% contains the actual number of collected args.
+%
+% @remark This macro checks for the end-of-input indicator, \pgfmanual@EOI. In case it encounters
+% \pgfmanual@EOI, it
+% 1. stops collecting, leaving the \pgfmanual@EOI as next token to be read,
+% 2. sets \ifpgfmanualprettyprinterarghasunmatchedbraces to \iftrue if necessary,
+% 3. assigns \pgfmanualprettyprinternumcollectedargs
+% 4. invokes the finish routine.
+% The \pgfmanual@EOI needs to be collected by following routines in
+% this case. You can also use \pgfutil@ifnextchar\pgfmanual@EOI{}{} in
+% following routines to check for \pgfmanual@EOI.

+% 1.2 (Nov 3, 2016)
+% - It's been a while :) Integrated a patch submitted by Jan Strunk <jan.strunk@uni-koeln.de>
+% (thanks a lot Jan!) fixing a bug with the behavior of "edge end x offset".
+%
% 1.1 (Jan 17, 2012)
% - Added the possibility to use simple arcs as edges (keys: arc edge/segmented edge)
% - Added "edge start x offset" and "edge end x offset" to fine tune edge start/end point position
% - Added \depstyle to define styles more easily
-% - Added "simple" theme, based on the parse on page 1 of [Nivre and McDonald, 2008 ACL-HLT]
+% - Added "simple" theme, based on the parse on page 1 of [Nivre and McDonald, 2008 ACL-HLT]
% - Added instructions to draw bubble parses
% - Fixed bug that would cause groupedges not to be straight under some circumstances;
