+.SH "DESCRIPTION"

+\fBdnet\fP

+is a simple test program for the

+dnet(3)

 library. It can be used to compose and transmit network datagrams as a

 Unix-style filter (e.g. reading from or writing to files and pipes) or

 modify the local system network configuration (including the ARP

 cache, firewall ruleset, network interfaces, and routing table).
