14Description:
15		The telem<x> directory contains files describing an instance of
16		a PMT telemetry device that exposes hardware telemetry. Each
17		telem<x> directory has an associated telem file. This file
18		may be opened and mapped or read to access the telemetry space
19		of the device. The register layout of the telemetry space is
20		determined from an XML file that matches the PCI device id and
21		GUID for the device.
