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