  19 # For each automake test case that checks features of the TESTS automake
  20 # interface, generate a sibling test that does likewise, but with the
  21 # option `parallel-tests' enabled.  Individual tests can prevent the
  22 # creation of such a sibling by explicitly setting the `$parallel_tests'
  23 # variable to either "yes" or "no".  The rationale for this is that if
  24 # the variable is set to "yes", the test already uses the `parallel-tests'
  25 # option, so that a sibling would be just a duplicate; while if the
  26 # variable is set to "no", the test doesn't support, or is not meant to
  27 # run with, the `parallel-tests' option, and forcing it to do so in the
  28 # sibling would likely cause a spurious failure.
