The NetPacket::* group of modules defines a framework for decoding and
encoding network packets in Perl.  Unlike other products on the
market, NetPacket requires no XS code and is written in 100% Perl.
Obviously, a method for generating packet data, such as the Net::Pcap
module, is needed.

The following protocols have been implemented:

        - Ethernet (802.3 and 802.2)
        - ARP
        - ICMP
        - IGMP
        - IP
        - UDP
        - TCP

It's pretty easy to add new protocols.  Just copy one of the existing
modules and figure out an unpack string which will unpack the
information in the packet and store the data into fields in the
namespace of the NetPacket::whatever object.  More information can be
found in the NetPacket(3) manpage, which is the base class module.

In this initial version, protocol encoding is not implemented.  Sorry!


Tim.
