Change CL 153869 added a help message when there are leftover arguments, as that used to invoke the command-line interface that is now gone. But the example in the help text (go doc -all net/http) generates a huge amount of output. Use a very simple, small-output example instead, to illustrate how to solve the problem without scrolling the program description hundreds of screenfuls away.

godoc on Google App Engine
==========================
Prerequisites
-------------
* Google Cloud SDK
https://cloud.google.com/sdk/
* Redis
* Go sources under $GOROOT
* Godoc sources inside $GOPATH
(go get -d golang.org/x/tools/cmd/godoc)
Running locally, in production mode
-----------------------------------
Build the app:
go build -tags golangorg
Run the app:
./godoc
godoc should come up at http://localhost:8080
Use the PORT environment variable to change the port:
PORT=8081 ./godoc
Running locally, in production mode, using Docker
-------------------------------------------------
Build the app's Docker container:
make docker-build
Make sure redis is running on port 6379:
$ echo PING | nc localhost 6379
+PONG
^C
Run the datastore emulator:
gcloud beta emulators datastore start --project golang-org
In another terminal window, run the container:
$(gcloud beta emulators datastore env-init)
docker run --rm \
--net host \
--env GODOC_REDIS_ADDR=localhost:6379 \
--env DATASTORE_EMULATOR_HOST=$DATASTORE_EMULATOR_HOST \
--env DATASTORE_PROJECT_ID=$DATASTORE_PROJECT_ID \
gcr.io/golang-org/godoc
godoc should come up at http://localhost:8080
Deploying to golang.org
-----------------------
Make sure you're signed in to gcloud:
gcloud auth login
Build the image, push it to gcr.io, and deploy to Flex:
make cloud-build deploy
Point the load balancer to the newly deployed version:
(This also runs regression tests)
make publish
Stop and/or delete down any very old versions. (Stopped versions can be re-started.)
Keep at least one older verson to roll back to, just in case.
You can also migrate traffic to the new version via this UI.

Troubleshooting
---------------
Ensure the Cloud SDK is on your PATH and you have the app-engine-go component
installed (gcloud components install app-engine-go) and your components are
up-to-date (gcloud components update)
