I've always been a bit curious about the rationale of the naming of site-packages. What does site mean in this context? I doubt it means 'website', and I've never heard 'site' used in relation to the installation location, or the context of the machine.
Any ideas?
It is a good question, and I don't know the answer. But I do have heard "site" as a way to name the combination of OS, installed software and/or physical computer. See for example http://www.pathname.com/fhs/pub/fhs-2.3.html , where they use the term a lot.
