# 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.

# A little confusing).  Thus allow these files to be added from the environment

# What files should we include?  A simple rule might be just those files under
# SCM control, however this would miss files we create like the opcodes and
# CClassHeaders.  The following attempts to find everything that is *useful*.
# (.del files are created by sccsrm, demo directories contain many .java files
# that probably aren't useful for development, and the pkgarchive may contain
# duplicates of files within the source hierarchy).  The ordering of the .raw
# file is an attempt to make cscope display the most relevant files first.
