a simple implement of pacp parser, for TCP only, in 200 lines of python
theirs code too long, try this one.
the main parse logic is based on : https://github.com/xiaxiaocao/pyhttpcap, thanks @xiaxiaocao
usage:
from pypcap import PcapFile
pcap = PcapFile('test.pcap')
for p in pcap.tcp_packets():
print p
result:
$ python pypcap/__init__.py
