   4 #
   5 # Usage:
   6 # # Copy the script, so it doesn't change during bisection
   7 # cp scripts/test/chutney-git-bisect.sh .
   8 # git bisect run \
   9 #   ./chutney-git-bisect.sh [tries [build-dir [flavour [skip-flavour]]]]
  10 #
  11 # Runs chutney up to <tries> times (default 3), because some bugs involve race
  12 # conditions.
  13 # Changes to <build-dir> (default no cd) before running tests.
  14 # Runs chutney network <flavour> (default make test-network-all) as the test.
  15 # Skips the test if <skip-flavour> fails (default no skip).
