+# ===========================================================================
+#     https://www.gnu.org/software/autoconf-archive/ax_code_coverage.html
+# ===========================================================================
+#
+# SYNOPSIS
+#
+#   AX_CODE_COVERAGE()
+#
+# DESCRIPTION
+#
+#   Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
+#   CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LIBS which should be included
+#   in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LIBADD 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.
+#
+#   Test also for gcov program and create GCOV variable that could be
+#   substituted.
+#
+#   Note that all optimization flags in CFLAGS must be disabled when code
+#   coverage is enabled.
+#
+#   Usage example:
+#
+#   configure.ac:
+#
+#     AX_CODE_COVERAGE
+#
+#   Makefile.am:
+#
+#     @CODE_COVERAGE_RULES@
+#     my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ...
+#     my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
+#     my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
+#     my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
+#
+#   This results in a "check-code-coverage" rule being added to any
+#   Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module
+#   has been configured with --enable-code-coverage). Running `make
+#   check-code-coverage` in that directory will run the module's test suite
+#   (`make check`) and build a code coverage report detailing the code which
+#   was touched, then print the URI for the report.
+#
+#   In earlier versions of this macro, CODE_COVERAGE_LDFLAGS was defined
+#   instead of CODE_COVERAGE_LIBS. They are both still defined, but use of
+#   CODE_COVERAGE_LIBS is preferred for clarity; CODE_COVERAGE_LDFLAGS is
+#   deprecated. They have the same value.
+#
+#   This code was derived from Makefile.decl in GLib, originally licenced
+#   under LGPLv2.1+.
