    # # Ruby Client for Stackdriver Debugger API ([Alpha](https://github.com/GoogleCloudPlatform/google-cloud-ruby#versioning))
    #
    # [Stackdriver Debugger API][Product Documentation]:
    # Examines the call stack and variables of a running application
    # without stopping or slowing it down.
    # - [Product Documentation][]
    #
    # ## Quick Start
    # In order to use this library, you first need to go through the following
    # steps:
    #
    # 1. [Select or create a Cloud Platform project.](https://console.cloud.google.com/project)
    # 2. [Enable the Stackdriver Debugger API.](https://console.cloud.google.com/apis/api/debugger)
    # 3. [Setup Authentication.](https://googlecloudplatform.github.io/google-cloud-ruby/#/docs/google-cloud/master/guides/authentication)
    #
    # ### Next Steps
    # - Read the [Stackdriver Debugger API Product documentation][Product Documentation]
    #   to learn more about the product and see How-to Guides.
    # - View this [repository's main README](https://github.com/GoogleCloudPlatform/google-cloud-ruby/blob/master/README.md)
    #   to see the full list of Cloud APIs that we cover.

          # The Debugger service provides the API that allows users to collect run-time
          # information from a running application, without stopping or slowing it down
          # and without modifying its state.  An application may include one or
          # more replicated processes performing the same work.
          #
          # A debugged application is represented using the Debuggee concept. The
          # Debugger service provides a way to query for available debuggees, but does
          # not provide a way to create one.  A debuggee is created using the Controller
          # service, usually by running a debugger agent with the application.
          #
          # The Debugger service enables the client to set one or more Breakpoints on a
          # Debuggee and collect the results of the set Breakpoints.
