Some notes on how to format the documentation.

doc/ZConfig/README.txt

+The zconfig.tex document in this directory contains the reference
+documentation for the ZConfig package.  This documentation is written
+using the Python LaTeX styles.
+
+To format the documentation, get a copy of the Python documentation
+tools (the Doc/ directory from the Python sources), and create a
+symlink to the tools/mkhowto script from some convenient bin/
+directory.  You will need to have a fairly complete set of
+documentation tools installed on your platform; see
+
+    http://www.python.org/doc/current/doc/doc.html
+
+for more information on the tools.
