  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.

  79 # (demo directories contain many .java files

  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.
