I would recommend just naming the file circle.py, and defining something 
like a variable named __version__ or maybe __revision__ at the top of 
the module. Then you can, I don't know, back up your old versions to 
other filenames or something.

Or, if you really want to do this right, you could install Subversion. :-)
