  # Ignore run.cpp and subrun.cpp for code coverage.  These files are essentially impossible to test
  # with deterministic unit tests (all MCMC moves involve randomness, and the definition of "correct"
  # is "do they sample the correct distribution?", which doesn't translate easily to an assertion).
  # Over time, the intent is to move as much deterministic "machinery" out of these files as possible,
  # and ensure that machinery is covered well by unit tests.
