32 <para><application>HAL</application> is a hardware abstraction layer, which
33 is a piece of software that provides a view of the various hardware
34 attached to a system. In addition to this, <application>HAL</application>
35 keeps detailed metadata for each piece of hardware and provides hooks such
36 that system and desktop-level software can react to changes in the hardware
37 configuration in order to maintain system policy. The most important goal
38 of <application>HAL</application> is to provide plug-and-play facilities
39 for UNIX-like desktops with focus on providing a rich and extensible
40 description of device characteristics and features.</para>
