#.rst:
# ECMCoverageOption
# --------------------
#
# Allow users to easily enable GCov code coverage support.
#
# Code coverage allows you to check how much of your codebase is covered by
# your tests. This module makes it easy to build with support for
# `GCov <https://gcc.gnu.org/onlinedocs/gcc/Gcov.html>`_.
#
# When this module is included, a ``BUILD_COVERAGE`` option is added (default
# OFF). Turning this option on enables GCC's coverage instrumentation, and
# links against ``libgcov``.
#
# Note that this will probably break the build if you are not using GCC.
#
# Since 1.3.0.
