// CHANGELOG
//  v0.1.3: added license block and modified namespace (18 Jun 2008)
//  v0.1.2: list of @includes and @excludes is bare-bones, but works with current woot/yahoo implementation (2 Apr 2008)
//  v0.1 fixed @include and @exclude so it doesn't perform the redirect when browsing other portions of the site
