For the uninitiated, while vim comes with ctrl-] out of the box, it
doesn't actually know where something is defined unless there's at least one `tags` file and you've told vim
where to find it/them. You can run `ctags` manually, but this can get tiresome if you want vim to

I can now very quickly navigate to where whatever's under my cursor was defined
with a single keystroke. What's nice about this usage of ctags is 1) it runs in the background and never
interrupts you, 2) it's fast, and 3) it runs every time you save.

<code>gf</code> bridges a significant gap that ctags don't cover:
It stands for "go to file". Type <code>gf</code> in normal mode when your cursor's over a filename, and it opens it!

As mentioned above, you can tell vim about multiple <code>tags</code> files in multiple paths. It
doesn't come up as often that I want to "go to definition" of library code, but I can see how it
might come in handy.
