This software was developed for an article on writing your own NIS
servers (Sun/Expert magazine.) It implements a simple server I call
the "Yeats Poetry" server, or yp server for short.
The server uses two NIS maps, one to return poems based on title and
the other by first line. The NIS maps are created by the two shell
scripts in this directory, bytitle and byfirst respectively. The
sample query program (yeats.c) also implements searching for all poems
which contain a text pattern (uses regular expressions.)
