This is a heroku buildpack for Pelican.

$ heroku config:set BUILDPACK_URL=https://github.com/getpelican/heroku-buildpack-pelican

To allow this buildpack to redirect any secondary domains, you can define the environmental variable PELICAN_SITEURL.

$ heroku config:set PELICAN_SITEURL=http://getpelican.com

Now any requests to http://pelican.herokuapp.com or http://www.getpelican.com will redirect to the SITEURL.
