449 | # There should be an assembly language file named FILE.s in the test |

452 | # `nm' on the .o file to produce textual output, and then analyze that | |
453 | # with regexps. The FILE.d file specifies what program to run, and | |

455 | # | |
456 | # The FILE.d file begins with zero or more option lines, which specify | |
