+output in your LaTeX documents in a single compilation run.  LaTeX documents
+must be compiled with LuaLaTeX for this to work.  PyLuaTeX runs a Python
+InteractiveInterpreter (actually several if you use different sessions) in the
+background for on-the-fly code execution.  Python code from your LaTeX file is
+sent to the background interpreter through a TCP socket.  This approach allows
+your Python code to be executed and the output to be integrated in your LaTeX
+file in a single compilation run.")
