  # The location to the Phusion Passenger root directory. This
  # configuration option is essential to Phusion Passenger. The correct
  # value is given by the installer, and should usually not be changed
  # manually.
  #
  # This required option may only occur once, in the global server
  # configuration.
  #
  # The config variable got moved to its own file that will get updated by
  # the package.

  # Passenger should write to the Apache error log file. A higher log
  # level value means that more information will be logged.
  #
  # Possible values are:
  #
  # 0: Show only errors and warnings.
  #
  # 1: Show the most important debugging information. This might be useful
  #    for system administrators who are trying to figure out the cause
  #    of a problem.
  #
  # 2: Show more debugging information. This is typically only useful for
  #    developers.
  # 3: Show even more debugging information.
  #
  # This option may only occur once, in the global server configuration.
  #
  # The default is 0.

  # configuration option allows one to specify which user Rails/Rack
  # applications must run as, if user switching fails or is disabled.

  #
  # The default value is nobody.
