   2 * `0` or `false` - Disables the target.
   3 * `1` or `true` - Writes to `STDERR`.
   4 * `[2-9]` - Writes to the already opened file descriptor.
   5 * `<absolute-pathname>` - Writes to the file in append mode. If the target
   6 already exists and is a directory, the traces will be written to files (one
   7 per process) underneath the given directory.
   8 * `af_unix:[<socket_type>:]<absolute-pathname>` - Write to a
   9 Unix DomainSocket (on platforms that support them).  Socket
  10 type can be either `stream` or `dgram`; if omitted Git will
  11 try both.
