    (description
     "Iproute2 is a collection of utilities for controlling TCP/IP
networking and traffic with the Linux kernel.

Most network configuration manuals still refer to ifconfig and route as the
primary network configuration tools, but ifconfig is known to behave
inadequately in modern network environments.  They should be deprecated, but
most distros still include them.  Most network configuration systems make use
of ifconfig and thus provide a limited feature set.  The /etc/net project aims
to support most modern network technologies, as it doesn't use ifconfig and
allows a system administrator to make use of all iproute2 features, including
traffic control.

iproute2 is usually shipped in a package called iproute or iproute2 and
consists of several tools, of which the most important are ip and tc.  ip
controls IPv4 and IPv6 configuration and tc stands for traffic control.  Both
tools print detailed usage messages and are accompanied by a set of
manpages.")
