331 | 8 This finds all scripts in the test directory named test-* and executes |
9 them. The scripts can be either shell scripts or Python. Each test is | |
10 run in a temporary directory that is removed when the test is complete. | |

13 matches test-<x>.out. If the new output doesn't match, it is stored in | |
14 test-<x>.err. | |
