This buildpack should be included as part of Heroku apps that host API documentation.
For more info on how buildpacks work, read the Heroku Buildpacks API: https://devcenter.heroku.com/articles/buildpack-api
The detect script in ./bin/detect
will test for the existence of the boxt_documentation gem on the system. If it's not found, the buildpack will exit, otherwise it will run the script in ./bin/compile
.
The compile script will run the requisite rake tasks on the boxt_documentation gem to build the API documentation.
