aoqi@0: #
aoqi@0: # Things to note:
aoqi@0: #	1. We use relative names for cscope.
aoqi@0: #	2. We *don't* remove the old cscope.out file, because cscope is smart
aoqi@0: #	   enough to only build what has changed.  It can be confused, however,
aoqi@0: #	   if files are renamed or removed, so it may be necessary to manually
aoqi@0: #	   remove cscope.out if a lot of reorganization has occurred.
