site_url() vs home_url() info check

[justintadlock]

I think it might be worth adding a quick info check for the use of site_url(). I've come across a few themes that were using it when they should've been using home_url().

Info check should read something like:

Theme is using site_url(). site_url() references the URL where the WordPress files are located. Use home_url() if the intention is to point to the site address (home page).
