%description
The packetdrill scripting tool enables quick, precise tests for entire 
TCP/UDP/IPv4/IPv6 network stacks, from the system call layer down to the NIC
hardware. packetdrill currently works on Linux, FreeBSD, OpenBSD, and NetBSD.
It can test network stack behavior over physical NICs on a LAN, or on a single
machine using a tun virtual network device.
