++This module matches certain packets in P2P flows. It is not
++designed to match all packets belonging to a P2P connection - 
++use IPP2P together with CONNMARK for this purpose. Also visit
++http://www.ipp2p.org for detailed information.
++
++Use it together with -p tcp or -p udp to search these protocols
++only or without -p switch to search packets of both protocols.
++
++IPP2P provides the following options:
++.TP
++.B "--edk "
++Matches as many eDonkey/eMule packets as possible.
++.TP
++.B "--kazaa "
++Matches as many KaZaA packets as possible.
++.TP
++.B "--gnu "
++Matches as many Gnutella packets as possible.
++.TP
++.B "--dc "
++Matches as many Direct Connect packets as possible.
++.TP
++.B "--bit "
++Matches BitTorrent packets.
++.TP
++.B "--apple "
++Matches AppleJuice packets.
++.TP
++.B "--soul "
++Matches some SoulSeek packets. Considered as beta, use careful!
++.TP
++.B "--winmx "
++Matches some WinMX packets. Considered as beta, use careful!
++.TP
++.B "--ares "
++Matches Ares and AresLite packets. Use together with -j DROP only.
++.TP
++.B "--ipp2p "
++Short hand for: --edk --kazaa --gnu --dc
++.TP
++.B "--debug "
++Prints some information about each hit into kernel logfile. May 
++produce huge logfiles so beware!
