+Building DEB packages
+=====================
+
+REQUIREMENTS:
+    You will need a working Internet connection to execute the build, because
+    the build procedure for the included "dpdk" project attempts to contact the
+    Internet host "dpdk.org".
+
+There are three main parts to the process:
+    a) Stage the source tree so that dpkg-source will recognize its organization
+        and create a valid DSC source package for you;
+    b) Ensure that the tools required for building DEB packages are installed;
+        and
+    c) Launch the build.
+
+1) Create, or have on hand, a local clone of the git repository, with no
+untracked files or local modifications pending, up-to-date with the branch or
+commit reference from which you wish to construct the source release.
+
+The branch and repository origins will differ based on local conditions.
+
+Example:
+$ git clone -b master ssh://git@example.com:7999/~username/open-vpp
+
+("-b master" can be omitted since master is the default branch)
+
+2) Rename the checkout with a version number embedded in its name as is
+conventional for code releases.  Again, your version number may vary.
+
+Example:
+$ mv open-vpp open-vpp-0.0.0
+
+3) Ensure that the dpkg-buildpackage program is installed.
+
+E.g.,
+
+# apt-get install dpkg-dev
+
+4) From the PARENT directory of the debian/ directory, run:
+
+$ cd open-vpp-0.0.0
+$ dpkg-buildpackage -I .git -us -uc
+
+(The -us and -uc flags omit GPG signatures from the .dsc and .changes files,
+respectively.  You can add them later, or if you are preparing a signed release
+and have the signing key on hand, leave off the flags.)
+
+5) Get rid of the source directory; you now either have a source package with
+which you can re-create it at any time, or there were problems with the build,
+and you should go back to your git checkout to fix them.
+
+$ rm -r open-vpp-0.0.0
+
+END

+To run vpp with the debug shell:
+
+sudo vpe unix interactive
+
+which will result in a prompt that looks like:
+
+DBGvpd#
+
+To give it a spin, we can create a tap interface and try a simple ping
+(with trace).
+
+To create the tap:
+
+DBGvpd# tap connect foobar
+Created tap-0 for Linux tap 'foobar'
+DBGvpd# show int
+
+To assign it an ip address (and 'up' the interface):
+
+DBGvpd# set int ip address tap-0 192.168.1.1/24
+DBGvpd# set int state tap-0 up
+
+To turn on packet tracing for the tap interface:
+DBGvpd# trace add tapcli-rx 10
+
+Now, to set up and try the other end from the unix prompt:
+vagrant@vagrant-ubuntu-trusty-64:~$ sudo ip addr add 192.168.1.2/24 dev foobar
+vagrant@vagrant-ubuntu-trusty-64:~$ ping -c 3 192.168.1.1
+
+To look at the trace, back in the vpp CLI:
+DBGvpd#  show trace
+
+And to stop tracing:
+
+DBGvpd# clear trace
+
+Other fun things to look at:
+
+The vlib packet processing graph:
+DBGvpd# show vlib graph
+
+which will produce output like:
+
+           Name                      Next                    Previous
+ip4-icmp-input                  error-punt [0]               ip4-local

+This package contains the header files and static libraries for

+allocator (mheap.c), extendable printf-like interface built on top of vectors
+(format.c), formats for data structures (std-formats.c), and support for clock
+time-based function calls (timer.c).

+To run vpp with the debug shell:
+
+sudo ~vagrant/git/vpp/build-root/install-vpp_debug-native/vpp/bin/vpe unix interactive
+
+which will result in a prompt that looks like:
+
+DBGvpd#
+
+To give it a spin, we can create a tap interface and try a simple ping
+(with trace).
+
+To create the tap:
+
+DBGvpd# tap connect foobar
+Created tap-0 for Linux tap 'foobar'
+DBGvpd# show int
+
+To assign it an ip address (and 'up' the interface):
+
+DBGvpd# set int ip address tap-0 192.168.1.1/24
+DBGvpd# set int state tap-0 up
+
+To turn on packet tracing for the tap interface:
+DBGvpd# trace add tapcli-rx 10
+
+Now, to set up and try the other end from the unix prompt:
+vagrant@vagrant-ubuntu-trusty-64:~$ sudo ip addr add 192.168.1.2/24 dev foobar
+vagrant@vagrant-ubuntu-trusty-64:~$ ping -c 3 192.168.1.1
+
+To look at the trace, back in the vpp CLI:
+DBGvpd#  show trace
+
+And to stop tracing:
+
+DBGvpd# clear trace
+
+Other fun things to look at:
+
+The vlib packet processing graph:
+DBGvpd# show vlib graph
+
+which will produce output like:
+
+           Name                      Next                    Previous
