|

| 30 | # 1. We use relative names for cscope.
|
|---|
| 31 | # 2. We *don't* remove the old cscope.out file, because cscope is smart
|
|---|
| 32 | # enough to only build what has changed. It can be confused, however,
|
|---|
| 33 | # if files are renamed or removed, so it may be necessary to manually
|
|---|
| 34 | # remove cscope.out if a lot of reorganization has occurred.
