define Package/snort3/description
  Snort is an open source network intrusion detection and prevention system.
  It is capable of performing real-time traffic analysis, alerting, blocking
  and packet logging on IP networks.  It utilizes a combination of protocol
  analysis and pattern matching in order to detect anomalies, misuse and
  attacks.
