Basic process flow:

    Dependencies -- once per compile machine
    ----------------------------------------
    sudo apt-get install -y \
        dh-make devscripts dh-autoreconf \
        libboost-all-dev \
        oracle-java7-installer \
        swig

    Common variables used below
    ---------------------------
    export PN="opendnp3"
    export PV="1.1.2"
    export P="${PN}-${PV}"
    export ORIG_TARBALL="${PN}_${PV}.orig.tar.gz"

    Step 1 - create the .orig.tar.gz file
    -------------------------------------
    git clone github:sentient-energy/dnp3.git ${P}

    rm -rf ${P}/debian/ ${P}/.git

    tar cfz ${ORIG_TARBALL} ${P}

    rm -rf ${P}

    Step 2 - create the DEB(s)
    --------------------------
    git clone github:sentient-energy/dnp3.git ${P}

    cd ${P}

    debuild -uc -us

    Step 3 - get the DEB(s)
    -----------------------
    cd ..

    ls -la *.deb
