Use revision control annotation in your editor

I was discussing comments vs. intention-revealing code with some folks on Twitter today and I realize that there’s a tool I take so much for granted I don’t even think about it any more. The tool is called VC-Annotate in Emacs, but some form of it should exist in every decent editor.

If you’re a programmer and you’re not using your editor’s revision control annotation features, I strongly recommend learning about them ASAP. They are an essential tool in understanding the story behind the code.
