+% BUGS:
+% 1. If anything gets send to stderr then it should be included
+% in \begin{verbatim}...\end{verbatim} to be properly displayed
+%
+% \immediate\write18{cat \@pythoninclude\space\jobname.py | python > \jobname.py.out 2>\jobname.py.err}
+%
+% 2. Watch out for indentation done by aucTeX in Emacs
+%
+% 3. Let the package accept a "final version" option, such
+% that the output of each python run is saved such that it can be
+% inserted into the document by hand 
+% (conference, journals are not likely to compile with
+% shell_escape or have python).
+%
+% 4. Somehow cache the output for each \begin{python}...\end{python}
+% and reuse the cached version if it has not changed.
+% Perhaps dangerous if the included python script has changed
+% but we would check for that as well.
