A buildpack that installs PrinceXML on Heroku.
Default version is 11.4.
Set $PRINCE_VESION to another valid version to over-ride this (
heroku config:set PRINCE_VERSION)
Set your license file to $PRINCE_LICENSE (
heroku config:set PRINCE_LICENSE)
This buildpack caches the output between runs to speed up deployment. If you need to clear the cache for some reason use the heroku-repo plugin
Copy the snippet above into CLI.
