Hmm, I already have a shell alias that does 90% of this. Doesn't parse .gitignore, but it's not a big problem for me. If it was I'd do `make clean` in the project.

This is always installed and ready to go on any box I have my dotfiles.

I suppose that is why it is hard for these perfectly-good improvements have a hard time getting traction. Because the older stuff is still so flexible.
