"""Quick hack to move all the files in subfolders of the current folder into
the current directory and rename them in the order that a lexicographic search
encounters them. Not anywhere near general purpose, and is POSIX-dependent.

Really, I'm just putting this here so I don't have to rewrite it from scratch
some other time.
