# Short-Description: HAL is a daemon for managing information about the hardware on the system
# Description:       HAL is a hardware abstraction layer and aims to provide a live list of devices present 
#		     in the system at any point in time. HAL tries to understand both physical devices (such 
#	   	     as PCI, USB) and the device classes (such as input, net and block) physical devices have, 
#		     and it allows merging of information from so called device info files specific to a device. 
#		     HAL provides a network API through D-BUS for querying devices and notifying when things 
#		     change. Finally, HAL provides some monitoring (in an unintrusive way) of devices, presently 
#		     ethernet link detection and volume mounts are monitored. This, and more, is all described 
#		     in the HAL specification
#
