Import tcpick from pkgsrc-wip.  Packaged by Jose Diaz Fernandez, and
modified by me.

tcpick is a textmode sniffer that can track TCP streams and saves the
data captured in files or displays them in the terminal.  It is useful
for picking files in a passive way.  It can store all connections in
different files, or it can display all the stream on the terminal
(using colors too).
