Welcome to my dotfiles! First things first, your mileage may vary greatly.
Good question. In the past, this repository has almost never looked like the dotfiles on my machines. This has been due in large part to hacks and shims that I added to get something working on a particular machine which I did not feel deserved to be committed to the repository.
That said, I am making a concerted effort to synchronize the dotfiles I use on a daily basis with this repository.
