# 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
