# some versions of genhtml support the --no-function-coverage argument,
# which we want. The problem w/ function coverage is that every template
# instantiation of a method counts as a different method, so if we
# instantiate a method twice, once for testing and once for prod, the method
# is tested, but it shows only 50% function coverage b/c it thinks we didn't
# test the prod version.
