I'm the author of Redis in Action, and over the last couple weeks whenever I've had some spare time, I've been working on a few side-projects (I know others exist, but I don't like the way they are structured or the way they work). One of them required that I build an object-Redis mapper for Python. When I started to want to use it in another project, I decided it was time to polish it up and release it.

I've got to head to the office in a few minutes, but I'll be happy to answer any questions when I get in.
