Leonardo is the Python code that has run jtauber.com since 2003.
It started off as an extensible content management system, architected in a RESTful style and initially focused on providing for personal websites with a password-protected wiki and weblog (including Atom feed).
Up to and including 0.7, it ran as CGI and used the filesystem as a database.
In 2007, I decided I'd stop investing work in my own web framework and did a crude port to Django (see jtauber.com Switches to Django).
In November 2011, I made the code Pinax-compatible. I'll likely replace it with Pinax's own biblion app soon.
