Feature: Configuration via YAML

  The application should process configuration options via YAML. These options
  should override hard coded defaults but not command line options.

  Config files are read from multiple locations in order of priority.  Once a
  config file is found, all other config files are ignored.


  Config file priority:

      ./repo.conf
      ./.repo.conf
      ./repo_manager/repo.conf
      ./.repo_manager/repo.conf
      ~/.repo.conf
      ~/repo.conf
      ~/repo_manager/repo.conf
      ~/.repo_manager/repo.conf

  All command line options can be read from the config file from the "options:"
  block. The "options" block is optional.

  NOTE: All file system testing is done via the Aruba gem.  The home folder
  config file is stubbed to prevent testing contamination in case it exists.


  Scenario: Specified config file exists
    Given an empty file named "config.conf"
    When I run `repo list --verbose --config config.conf`
    Then the output should contain:
      """
      config file: config.conf
      """

  Scenario: Specified config file option but not given on command line
    When I run `repo list --verbose --config`
    Then the exit status should be 1
    And the output should contain:
      """
      missing argument: --config
      """

  Scenario: Specified config file not found
    When I run `repo path --verbose --config=config.conf`
    Then the exit status should be 1
    And the output should contain:
      """
      config file not found
      """

 Scenario: Ignoring the config file with the "--no-config" option
    Given a file named "repo.conf" with:
      """
      ---
      options:
        color: true
      """
    When I run `repo list --verbose`
    Then its output should contain:

      :color=>true
      """
    When I run `repo list --verbose --no-config`
    Then its output should contain:
      """
      :color=>"AUTO"

    And its output should not contain:

 Scenario: Reading options from specified config file, ignoring the
    default config file
