%description
Stenographer is a full-packet-capture utility for buffering packets to disk for
intrusion detection and incident response purposes. It provides a high-
performance implementation of NIC-to-disk packet writing, handles deleting those
files as disk fills up, and provides methods for reading back specific sets of
packets quickly and easily.
