+% 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)
