Heroku buildpack: curl with HTTP/2 support

This is a Heroku buildpack that shadows the system-provided curl executable and libcurl with a custom built version, most notably for its HTTP/2 support – provided by nghttp2.

It is not meant to be used standalone, just as an extra layer before the actual language buildpack.

Usage

See Heroku's documentation on multiple buildpacks.

Example for a Vapor app:

$ heroku buildpacks:set https://github.com/vapor-community/heroku-buildpack.git
$ heroku buildpacks:add https://github.com/vzsg/heroku-buildpack-curl-http2.git --index 1
$ git push heroku master
...

You can verify the installation using the following command:

$ heroku run "curl --version"
