// User:Quarl/redirector.js - "Redirector" application

// When you invoke the Redirector (through a tab), adds a new form to the // document. Start typing page names and press ENTER after each one. A table // will show the current status of each page (already a redirect, doesn't // exist, etc.), and if you click "Redirect!", the target page will be updated // to redirect to the current page.
