~/Dropbox/Mackup. For example, once you've ran
mackup backup your
.gitconfig file will live at
~/.gitconfig will be symlinked to it. That way all your precious dotfiles and app settings are synced to Dropbox. When it comes time to get another machine (presumably your next machine) setup, it's as easy as installing Mackup, and running
Laurent's notes from the readme:

I agree. There are a number of ways to backup your dotfiles, but Mackup is super simple, doesn't require sharing them on GitHub (if that's not your thing), and leverages Dropbox -- which you likely have on your machine anyways.
Check out the install instructions to get started. You might also consider reading this as well to learn exactly how Mackup does what it does. If you haven't yet, checkout the unofficial guide to dotfiles on GitHub while you're at it. There's more than one way to skin this cat.
