Package description:
This program reads and parses packets from the link layer through the
transport layer, dumping explicit header information along the way.
It is a lot like tcpdump from LBL except that I've made an effort to
dump every relevant header field possible. The overall structure of
the code is loosely based on tcpdump and I've lifted a few modules
from the tcpdump distribution when necessary, rather than re-inventing
the wheel. In particular, the address conversion hashing routines are
pretty much lifted verbatim, as well as the TCP options section.
