BUGS
     The  locations of files are subject to change without notice; the organiza-
     tion of your file system may vary.

     This list is incomplete.

     The Network Information Service (NIS) was	formerly  known  as  Sun  Yellow
     Pages  (YP).   The functionality of the two remains the same; only the name
     has changed.
