| 6 |
|
|---|
| 7 | - Multiple commands for the same (double-colon) target
|
|---|
| 8 | - Different prerequisites for targets: only out-of-date
|
|---|
| 9 | ones are rebuilt.
|
|---|
| 10 | - Double-colon targets that aren't the goal target.
|

| 11 |
|

| 12 | Then we do the same thing for parallel builds: double-colon
|
|---|
| 13 | targets should always be built serially.";
