|---|
| 30 | # Copying Makefile.pre to Makefile: |

|---|
| 33 | # Setup files after a -n option) |
|---|
| 34 | # - replace _MODLIBS_ by the list of libraries from Setup |
|---|
| 35 | # - for each object file mentioned in Setup, append a rule |
|---|
| 36 | # '<file>.o: <file>.c; <build commands>' to the end of the Makefile |
|---|
| 37 | # - for each module mentioned in Setup, append a rule |
