# The cscope.out file is made in the current directory and spans the entire
# source tree.
#
# 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.
