+dnl GNOME_CODE_COVERAGE
+dnl
+dnl Defines CODE_COVERAGE_CFLAGS and CODE_COVERAGE_LDFLAGS which should be
+dnl included in the CFLAGS and LIBS/LDFLAGS variables of every build target
+dnl (program or library) which should be built with code coverage support.
+dnl Also defines GNOME_CODE_COVERAGE_RULES which should be substituted in your
+dnl Makefile; and $enable_code_coverage which can be used in subsequent
+dnl configure output.
+dnl
+dnl Note that all optimisation flags in CFLAGS must be disabled when code
+dnl coverage is enabled.
+dnl
+dnl Derived from Makefile.decl in GLib, originally licenced under LGPLv2.1+.
+dnl This file is licenced under LGPLv2.1+.
+dnl
+dnl Usage example:
+dnl configure.ac:
+dnl GNOME_CODE_COVERAGE
+dnl
+dnl Makefile.am:
+dnl @GNOME_CODE_COVERAGE_RULES@
+dnl my_program_LIBS = … $(CODE_COVERAGE_LDFLAGS) …
+dnl my_program_CFLAGS = … $(CODE_COVERAGE_CFLAGS) …
+dnl
+dnl This results in a “check-code-coverage” rule being added to any Makefile.am
+dnl which includes “@GNOME_CODE_COVERAGE_RULES@” (assuming the module has been
+dnl configured with --enable-code-coverage). Running `make check-code-coverage`
+dnl in that directory will run the module’s test suite (`make check`) and build
+dnl a code coverage report detailing the code which was touched, then print the
+dnl URI for the report.

-dnl GNOME_CODE_COVERAGE
-dnl
-dnl Defines CODE_COVERAGE_CFLAGS and CODE_COVERAGE_LDFLAGS which should be
-dnl included in the CFLAGS and LIBS/LDFLAGS variables of every build target
-dnl (program or library) which should be built with code coverage support.
-dnl Also defines GNOME_CODE_COVERAGE_RULES which should be substituted in your
-dnl Makefile; and $enable_code_coverage which can be used in subsequent
-dnl configure output.
-dnl
-dnl Note that all optimisation flags in CFLAGS must be disabled when code
-dnl coverage is enabled.
-dnl
-dnl Derived from Makefile.decl in GLib, originally licenced under LGPLv2.1+.
-dnl This file is licenced under LGPLv2.1+.
-dnl
-dnl Usage example:
-dnl configure.ac:
-dnl GNOME_CODE_COVERAGE
-dnl
-dnl Makefile.am:
-dnl @GNOME_CODE_COVERAGE_RULES@
-dnl my_program_LIBS = … $(CODE_COVERAGE_LDFLAGS) …
-dnl my_program_CFLAGS = … $(CODE_COVERAGE_CFLAGS) …
-dnl
-dnl This results in a “check-code-coverage” rule being added to any Makefile.am
-dnl which includes “@GNOME_CODE_COVERAGE_RULES@” (assuming the module has been
-dnl configured with --enable-code-coverage). Running `make check-code-coverage`
-dnl in that directory will run the module’s test suite (`make check`) and build
-dnl a code coverage report detailing the code which was touched, then print the
-dnl URI for the report.
