// Command hostserver-gcp is a combined DirServer and StoreServer that serves a
// synthetic Upspin tree used to configure sub-domains under the domain
// upspin.services. Each Upspin user can set the IP address of one sub-domain,
// the name of which is a hash of their user name.
//
// Assuming the server is running as host@upspin.io, here's how the user
// user@example.com would configure their sub-domain:
//   $ upspin mkdir host@upspin.io/user@example.com/127.0.0.1
// If that command succeeds, their host name was created or updated.
// (This can be any command that performs a DirServer.Put to that path; the put
// command would work, but mkdir is the simpliest choice in this case.)
//
// To find the host name, the user issues a get request, which returns both the
// host name and configured IP address:
//   $ upspin get host@example.com/user@example.com
//   127.0.0.1
