ethereal-common 0.99.6rel-3ubuntu0.2 (lpia binary) in ubuntu gutsy

 Wireshark is a network traffic analyzer, or "sniffer", for Unix and
 Unix-like operating systems. A sniffer is a tool used to capture
 packets off the wire. Wireshark decodes numerous protocols (too many
 to list).
 .
 It was previously named ethereal. This is a transitional package
 so ethereal users get wireshark on upgrades. This package handles
 ethereal-common -> wireshark-common. It can be safely removed.
