Show hidden files in finder

There are many times when I want to see hidden files and folders when using my mac. When making changes to the Apache config is one of those times. So how do I make it so I can easily see those files? I found talk of this on this page:

Which has a link in one of the comments to this nifty little program:

I installed this and it makes it easy toggle on and off the ability to see hidden files and folders.
