title: Is it Possible to Alias Config Variables on Heroku?
body: <p>I'm currently writing a tutorial on setting up Wordpress on Heroku. Right now I'm using the <code>ClearDB</code> add-on which sets a <code>CLEARDB_DATABASE_URL</code> ENV variable automatically. Is it possible to alias the <code>ENV</code> variable through Heroku as <code>DATABASE_URL</code>?</p>
