This is a Heroku buildpack of CasperJS / PhantomJS.
Example usage:
$ heroku create --stack cedar --buildpack https://github.com/leesei/heroku-buildpack-casperjs.git

Alternately, you can cascade with other buildpacks:
$ heroku create --stack cedar --buildpack https://github.com/ddollar/heroku-buildpack-multi.git
$ echo https://github.com/leesei/heroku-buildpack-casperjs.git > .buildpacks
# echo [other buildpack] >> .buildpacks
# `git add` your files
$ git push heroku master
