 # DESCRIPTION
 #
-#   Defines CODE_COVERAGE_CFLAGS and CODE_COVERAGE_LDFLAGS which should be
-#   included in the CFLAGS and LIBS/LDFLAGS variables of every build target
-#   (program or library) which should be built with code coverage support.
-#   Also defines CODE_COVERAGE_RULES which should be substituted in your
-#   Makefile; and $enable_code_coverage which can be used in subsequent
-#   configure output. CODE_COVERAGE_ENABLED is defined and substituted, and
-#   corresponds to the value of the --enable-code-coverage option, which
-#   defaults to being disabled.
