Heroku Tesseract Custom Buildpack

heroku-buildpack-tesseract

Added the libraries to use Tesseract 3.02.02 on Heroku

This buildpack is built to be used through heroku-buildpack-multi. In your app you need to:

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

Then, create a .buildpacks file inside your app:

https://github.com/heroku/_YOUR_MAIN_BUILDPACK
https://github.com/ddollar/heroku-buildpack-apt
https://github.com/Papiel/heroku-buildpack-tesseract

Then creata a Aptfile file inside your app:

tesseract-ocr

See the documentation of heroku-build-multi for a detailed explanation how to use it.

bin/release outputs garbage which Heroku used to ignore but now craps out on

Using this buildpack now results in the following error message during deployment:

remote:  !     Push failed: failed to read buildpack metadata: string not matched
remote:  !     Please try pushing again.
remote:  !     If the problem persists, see http://help.heroku.com/ and provide Request ID e6a4b3b6-278e-4ab1-b113-a7187dc5b683.

This is because bin/release is supposed to output YAML but it just outputs the line release. The script can safely be omitted.
