deploying from a branch other than master

[Josh Taylor]

I'm not sure I understand what happens when I issue the command: gcloud preview app deploy. It seems to me like the code in the local repository is used for the build process and then the code from the google hosted git repository is used for actually running the app. If this is the case, how do I specify that I want it to use the code from a branch other than master? I kind of would expect to be able to do something like: gcloud preview app deploy --branch staging.
