+"""Command-line program to list the logs in a Google Cloud Platform project.
+
+Simple command-line program to demonstrate connecting to the Google Cloud
+Logging API to retrieve logs data, using application default credentials[1] to
+authenticate.
+
+This application will run--without modification--on 1) Google App Engine,
+2) Google Compute Engine, 3) a local Linux workstation with the Google Cloud
+SDK, or 4) a Linux computer without the SDK.
+
+In cases 1) and 2), authorization comes from a built-in service account on the
+instance running this application. In case 3) you must run "gcloud auth login"
+your workstation to authorize the application. In case 4) you must create a
+service account[2] in the Google Cloud project whose log data you will fetch,
+copy the account's JSON private key file to the computer running this
+application, and on that computer set the environment variable
+GOOGLE_APPLICATION_CREDENTIALS to point to the JSON private key file. For
+example:
+
+ $ export GOOGLE_APPLICATION_CREDENTIALS=/path/to/json-key.json
