#	Mnemonic:	pub_cov.ksh
#	Abstract:	This script will push any coverage files (.gcov) in the current
#				directory to the indicated target directory (/tmp/gcov_rpts by
#				default.  Because sonar needs to match the source listed in the
#				.gcov file with what it perceives was analysed by it's code, we
#				must fiddle the name in the .gcov file to be a path relative to
#				the project root.  For example, if the .gcov file has the line:
#
#						0:Source:mc_listener.c
#
#				we must change that to be the path of sidecars/listener/src
