+	  An implementation of the Point-to-point protocol over
+	  Ethernet.  Has userspace client and server deamons. You
+	  likely only need this package if you are implementing the
+	  pppoe server that will service other pppoe client
+	  devices. Otherwise the normal client functionality already
+	  exists in the pppd package (and kernel).
