Copybara should follow the XDG Base Directory Specification

[sudoforge]

The XDG Base Directory Specification defines base directories in which specified files should live. Of these, I think XDG_DATA_HOME (or ~/.local/share) makes the most sense for Copybara. My main motivation for this is to avoid the top-level copybara directory in my $HOME.

Yes, this would be really good. I would imagine there's probably a java package for this purpose.

@rpavlik i actually submitted a PR for this: #152

Unfortunately, @mikelalcon mentioned that several internal processes/tools depend on the current default output root. As such, I simply set an alias in my shell's RC file. You may benefit from doing the same:

I'm keeping this issue open as I do believe it is a valid feature request.
