| 9 ## Tries to test unlink (removal) and replacement rules. | |
| 10 ## | |

| 12 ## expected results are in _t_*.unlink and _t_*.replace. | |
| 13 ## The tests are listed below in the array, with the original | |
| 14 ## image and its expected good matching pattern, which is also | |
| 15 ## verified. The replacement image also set there. | |
