  optional_prefs: Pref files conditionally installed based on USE flags.
  powerd:         Power manager daemon running as the "power" user.
  powerd/policy:  High-level parts of powerd that make policy decisions.
  powerd/system:  Low-level parts of powerd that communicate with the kernel.
  tools:          Utility programs; may depend on powerd code.
  udev:           udev configuration files and scripts.
