    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

    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.
