What's the context of this?

If you stumbled upon this repository, it's in reference to this thread about how to push a go binary to heroku https://groups.google.com/forum/#!topic/golang-nuts/6tyCz7Tc8Ow/discussion I hope it helps you on your journey!

Example of a less Go server on heroku with a proper Go workspace

$ heroku create 
$ heroku config:add BUILDPACK_URL=https://github.com/kr/heroku-buildpack-go 
$ git push heroku master

This example compiles on heroku

The directory structure has two binaries, and a foobar.com/shared shared package that both to import.

src/foobar.com/frontend/  <-- there's a binary in here, the web one
src/foobar.com/shared/    <-- NO BINARY in here, just a package with shared code
src/foobar.com/worker/    <-- there's a second binary in here

.godir must be set to base path. In this case, foobar.com

Symlinks are used to expose the frontend, shared, and worker packages to the heroku buildpack.
