+
+ Deviations from upstream
+ ~~~~~~~~~~~~~~~~~~~~~~~~
+
+ This code is based on `dpkt code <https://code.google.com/p/dpkt/>`__ lead by Dug Song.
+
+ At this point, this is not the exact `upstream
+ version <https://code.google.com/p/dpkt/>`__. If you are looking for the
+ latest stock dpkt, please get it from the above link.
+
+ Almost all of the upstream changes are pulled. However, some modules are
+ not. Here is a list of the changes:
+
+ - `dpkt/dpkt.py <https://github.com/kbandla/dpkt/commit/336fe02b0e2f00b382d91cd42558a69eec16d6c7>`__:
+ decouple dnet from dpkt
+ - `dpkt/dns.py <https://github.com/kbandla/dpkt/commit/2bf3cde213144391fd90488d12f9ccce51b5fbca>`__
+ : parse some more DNS flags
+
+ Examples
+ --------
+
+ [@jonoberheide's](https://twitter.com/jonoberheide) old examples still
+ apply:
+
+ - `dpkt Tutorial #1: ICMP
+ Echo <https://jon.oberheide.org/blog/2008/08/25/dpkt-tutorial-1-icmp-echo/>`__
+ - `dpkt Tutorial #2: Parsing a PCAP
+ File <https://jon.oberheide.org/blog/2008/10/15/dpkt-tutorial-2-parsing-a-pcap-file/>`__
+ - `dpkt Tutorial #3: dns
+ spoofing <https://jon.oberheide.org/blog/2008/12/20/dpkt-tutorial-3-dns-spoofing/>`__
+ - `dpkt Tutorial #4: AS Paths from
+ MRT/BGP <https://jon.oberheide.org/blog/2009/03/25/dpkt-tutorial-4-as-paths-from-mrt-bgp/>`__
+
+ `Jeff Silverman <https://github.com/jeffsilverm>`__ has some
+ `code <https://github.com/jeffsilverm/dpkt_doc>`__ and
+ `documentation <http://www.commercialventvac.com/dpkt.html>`__.
