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

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