last year I was told to put version numbers in the program, and keep a consistent naming paradigm.
So of course my version number starts off as a 3, then the next one is 3.1, then 3.14, and as the version number approaches pi you get the newer files. You just have to look for the file with the longest string of digits. And the program will work flawlessly as soon its version number has all the digits of pi.
Let's just say I've been told not to do that again this year
