| * `0` or `false` - Disables the target. |
| * `1` or `true` - Writes to `STDERR`. |
| * `[2-9]` - Writes to the already opened file descriptor. |
| * `<absolute-pathname>` - Writes to the file in append mode. If the target |
| already exists and is a directory, the traces will be written to files (one |
| per process) underneath the given directory. |
| * `af_unix:[<socket_type>:]<absolute-pathname>` - Write to a |
| Unix DomainSocket (on platforms that support them). Socket |
| type can be either `stream` or `dgram`; if omitted Git will |
| try both. |
