+Maintaining Multiple FAQs
+-------------------------
+
+If you have multiple FAQs, you need a separate FAQDIR per FAQ, and a
+different customization file per FAQ.  The easiest thing to do would
+be to have the faqcust.py for each FAQ live in the FAQDIR for that
+FAQ, but that creates some security concerns, since the FAQDIR must be
+world writable: *if* someone who breaks into your system (or a
+legitimate user) manages to edit the faqcust.py file they can get
+arbitrary code to execute through the FAQ wizard.  Therefore, you will
+need a more complex setup.
+
+The best way is probably to have a directory that is only writable by
+you for each FAQ, where you place the copy of faqcust.py for that FAQ,
+and have a world-writable subdirectory DATA for the data.  You then
+set FAQDIR to point to the DATA directory and change the faqw.py
+bootstrap script to add FAQDIR/.. to sys.path (in front of SRCDIR, so
+the dummy faqcust.py from SRCDIR is ignored).
