To help increase my fluency in Python, I'm developing a simple sprite management system.
I am detailing the development process on my blog:
The project is hosted on Launchpad in a Bazaar repository.
https://code.launchpad.net/sprytes
You can get Bazaar here. I recommend downloading the standalone installer.
There are graphical front-ends similar to TortoiseSVN (such as TortoiseBZR), but I've had little luck with them. I use the command-line, it's not so bad. I recommend reading Bazaar in five minutes.
