heroku-buildpack-forge

Installs FORGEPACKAGES_AUTH for private packages if found in the environment
Creates an app/manage.py file if there isn't one (so Heroku collectstatic works like usual)
Adds a bin/post_compile script that the Python buildpack will use to compile Tailwind after the Forge packages have been installed (which contain Tailwind templates themselves)
Uses a default Procfile if one isn't present

Usage

Install the buildpack:

heroku buildpacks:add forgepackages/forge --index 1

Add FORGEPACKAGES_AUTH (optional):

heroku config:set FORGEPACKAGES_AUTH="<project_name>:<project_token>"
