  26 #
  27 #   Lines written to standard output matching /^(not )?ok\b/ must be
  28 #   interpreted as test lines. All other lines must not be considered
  29 #   test output.

  31 # Unfortunately, the exact format of TODO and SKIP directives is not as
  32 # clearly described in that manpage; but a simple reverse-engineering of
  33 # the prove(1) utility shows that it is probably given by the perl regex
  34 # /#\s*(TODO|SKIP)\b/.
