Update httpd.conf after upgrading to Mavericks

On OSX, the latest Mavericks update leaves you with a default httpd.conf, so you're greeted with the familiar "It Works!" when you navigate to localhost for the first time. Fortunately, the update saves your old httpd.conf backed up as httpd.conf.pre-update

It's an easy fix, just go to your terminal:

$ cd /etc/apache2/ ; sudo mv httpd.conf httpd.conf.mavericks ; sudo mv httpd.conf.pre-update httpd.conf ; sudo apachectl restart

And you're done!
