# Summerise the state of code coverage with gcovr and tweak the output
# to be more sane on Travis hosts. As we expect to be executed on a
# throw away CI instance we do spam temp files all over the shop. You
# most likely don't want to execute this script but just call gcovr
# directly. See also "make coverage-report"
