I've had a few requests for the Python code this site runs on so, over the weekend, I cleaned it up a little ready for a release. I then had to come up with a name. I'm over my "must include 'Py' in the name of every Python project" phase and wanted something that invoked the notion of a technologist's or scientist's notebook. It didn't take me long to come up with "Leonardo". And no sign of a name clash on either Freshmeat or Sourceforge. So, "Leonardo" it is.
I'm not sure it's ready for prime-time (although it's been running jtauber.com for almost a year) but if you have a lot of patience, you are more than willing to give it a try and I'd love your feedback.
Code is available from the Leonardo page. I'll incrementally put documentation there too - likely in response to user questions as they come in.
