   7 # BTW, i wrote a perl script that is similar to 'nfpipe' except that in
   8 # addition to logging to a file it provides a command line option for mailing
   9 # change notices to a group of users. Obviously you probably wouldn't want
  10 # to mail every change. But there may be certain directories that are commonly
  11 # accessed by a group of users who would benefit from an email notice.
  12 # Especially if they regularly beat on the same directory. Anyway if you
  13 # think anyone would be interested here it is.
