Custom buildpack that will install pdftk into /app/bin on Heroku. Supports cedar-14, heroku-16, and heroku-18.

1. Add this buildpack to your app.
2. Use /app/bin/pdftk. BTW, the default cedar-14 PATH includes /app/bin, so this might happen automatically.

Update the tarball_url line in scripts/build.sh

heroku create

heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-apt

git push heroku master

Now you'll have a new Heroku app on the default stack (currently cedar-14) that runs the scripts/build.sh script in this buildpack. That script will download the most recent PDFTK source and configure it with default options.

Use heroku logs -t to see when compilation is done. It'll start showing dots..

heroku open

1. Download the generated pdftk.zip
2. Chmod +x them
3. put them into bin/$STACK/ into this buildpack. $STACK shall be the name of your stack as given in the Heroku $STACK variable.

heroku ps:scale web=0 to turn off the dyno.
