This is a build pack for Middleman that will create your static site.
It is cleaner than most Middleman build packs out there because it takes advantage of Heroku Multiple Buildpacks to separate out the Ruby, Middleman and Web server specific components.
This build pack is meant to be used with the Heroku Multiple Buildpacks.
heroku buildpacks:add --index 1 heroku/ruby
heroku buildpacks:add --index 2 https://github.com/donbobka/heroku-buildpack-middleman
heroku buildpacks:add --index 3 https://github.com/heroku/heroku-buildpack-static
Then just push!
