 * @section edbus_intro_sec Introduction
 *
 * EDbus is a wrapper around the
 * <a href="http://www.freedesktop.org/wiki/Software/dbus">dbus</a>
 * library, which is a message bus system. It also implements a set of
 * specifications using dbus as interprocess communication.
 *
 * @section edbus_modules_sec Modules
 *
 * @li @ref EDbus_Group Wrapper around the dbus library, which
 * implementent an inter-process communication (IPC) system for
 * software applications to communicate with one another.
 * @li @ref EBluez_Group Implementation of the <a
 * href="http://www.bluez.org/">BlueZ</a> specifications, for wireless
 * communications with Bleutooth devices.
 * @li @ref EConnman_Group Implementation of the <a
 * href="http://connman.net/">connman</a> specifications, which
 * manages internet connections running the Linux operating system.
 * @li @ref EHal_Group Implementation of the <a
 * href="http://www.freedesktop.org/wiki/Software/hal">HAL</a>
 * specifications, which is a (software) layer between the hardware
 * devices of a computer and the softwares that run on that
 * computer (Hardware Abstraction Layer). HAL is deprecated, in favor
 * of DeviceKit.
 * @li @ref ENotify_Group To de described.
 * @li @ref EOfono_Group Implementation of the <a
 * href="http://ofono.org/">ofono</a> specifications, which is an
 * interface for mobile telephony applications.
 * @li @ref EUkit_Group Implementation of the <a
 * href="http://freedesktop.org/wiki/Software/DeviceKit">DeviceKit</a>
 * specifications, which is, like HAL, an Hardware Abstraction
 * Layer. DeviceKit is a replacement of the deprecated HAL system. It
 * has two submodules: UDisks, which manipulate storage devices, and
 * UPower, which manage power devices.
