https://cloud.google.com/pubsub/docs/reference/libraries#client-libraries-install-nodejs
says I should run npm install --save @google-cloud/pubsub

but https://googlecloudplatform.github.io/google-cloud-node/#/docs/google-cloud/0.45.0/pubsub
says npm install --save google-cloud

Which one should I use? Are they the same library? Can you align on only one?
