Good lord, I have never heard of the term "wheel of cheese", thanks! Probably because I rarely eat cheese. 20+ years of using Python on and off, and I finally understand what a "wheel" is.
Addendum: Every time I tried to understand Python packaging, I would come across the term "wheel" and my eyes would glaze over because I couldn't figure out what it was from context ("what the heck is a wheel?"). Maybe now I'll go back and finally understand Python packaging.
