# 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.

# 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*.

# (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.
