This is a copy of the original Gist found at https://gist.github.com/bhwebworks/5555641.

For some reason GitHub stopped allowing the original to be embedded, and since forking my own Gist isn't an option...

Added a variable for home_url() and the $scheme parameter to help with mixed http/https sites.
