5 | # There are five columns, separated by tabs. |

7 | # Column 1 contains the pattern, optionally enclosed in C<''>. |
8 | # Modifiers can be put after the closing C<'>. |
9 | # |
10 | # Column 2 contains the string to be matched. |
11 | # |
12 | # Column 3 contains the expected result: |
13 | # y expect a match |
14 | # n expect no match |
15 | # c expect an error |
24d786f4 |
16 | # T the test is a TODO (can be combined with y/n/c) |

21 | # Columns 4 and 5 are used only if column 3 contains C<y> or C<c>. |

26 | # interpolating that string after the match, or start of error message. |
