29 # Things to note:
|
|
|
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.
