@Title          Host Trace Buffer interface string format specifiers
@Copyright      Copyright (c) Imagination Technologies Ltd. All Rights Reserved
@Description    Header for the Host Trace Buffer logging messages. The following
                list are the messages the host driver prints. Changing anything
				but the first column or spelling mistakes in the strings will
                break compatibility with log files created with older/newer
                driver versions.
