This trivial App Engine app serves the small meta+redirector HTML pages for https://google.golang.org/. For example:

• https://google.golang.org/appengine
• https://google.golang.org/cloud
• https://google.golang.org/api/
• https://google.golang.org/api/storage/v1
• https://google.golang.org/grpc

The page includes a meta tag to instruct the go tool to translate e.g. the import path "google.golang.org/appengine" to "github.com/golang/appengine". See go help importpath for the mechanics.

To update the public site, run:

gcloud app --project=golang-org deploy --promote app.yaml
