| # An example hook script to check the commit log message. |
| 4 |
| # Called by "git commit" with one argument, the name of the file |
| 5 |
| # that has the commit message. The hook should exit with non-zero |
| 6 |
| # status after issuing an appropriate message if it wants to stop the |
| 7 |
| # commit. The hook is allowed to edit the commit message file. |
| 8 |
| # |

| # To enable this hook, rename this file to "commit-msg". |
| 10 |
| |
| 11 |
| # Uncomment the below to add a Signed-off-by line to the message. |

| # Doing this in a hook is a bad idea in general, but the prepare-commit-msg |
| 13 |
| # hook is more suited to it. |
