OK, I saw the devlog option, and that is indeed very nice. However, I was thinking about doing it through butler. I was thinking that the user could optionally append to the end of the butler command a string, or a handle to a file that represents a devlog to auto-upload or something. That way, you could, for example, create a devlog or changelog that, say, copies text that you already committed into a version control system.
It seems like it might be a cool feature to think about, anyway.
