## Description

The D-Bus Properties interface associates named properties with any D-Bus object.

The D-Bus Introspectable interface provides introspection information.

The D-Bus Peer interface is exported by every D-Bus object.

The Telepathy Properties interface associates a number of named properties with a channel, connection or other D-Bus object. Signals are emitted when the properties or their flags (readable/writable) change.
