Compute Engine samples need to be more comprehensive/updated

The sole sample at https://github.com/google/google-api-java-client-samples/tree/master/compute-engine-cmdline-sample covers listing instances, nothing else.

Can it be updated to cover other common cases like managing instance groups, autoscaling et al?

Also, the sample does not run with the latest version of your library. E.g. "com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp;" that is in the import does not seem to exist anymore.
