[10:39:55] <pradyunsg> gutsytechster: if you run `pip uninstall django` w/ Django installed -- you'll notice that it prints "site-packages/django/*" instead of listing all the files. That's what the "compress_for_rename" function does. :)
[10:41:30] <pradyunsg> gutsytechster: when you're not sure what a chunk of code does, try to look at the tests for the code. If they're written properly, they can provide hints as to what the code does.
[10:44:44] <pradyunsg> oh wait, I mis-spoke -- compress_for_rename is trying to minimize the number of rename calls we make; if we're moving all the files within a folder, we move the folder instead of trying to move every file one-by-one.
