This Buildpack helps Heroku build the LocoMotion demo site by configuring it to use a local version of the LocoMotion gem.
It is based off of the subdir-heroku-buildpack.
The main / useful file is bin/compile which copies the docs/demo
subdirectory to the correct place, and also copies the relevant LocoMotion gem
files into the docs/demo/vendor/loco_motion-rails directory where the demo
application expects it to live.
Make sure that this buildpack comes first in your list so that the files will be in the correct places when your Node / Ruby buildpacks run.
For local development, this is done with Docker volumes, but we need a different solution for Heroku.
