Packages for Gluon 2015.1 as used by Freifunk Gütersloh.

The whole picture, i. e. that's how it's build via Jenkins:

if [ ! -d gluon-2015.1-ffgt ]; then
    git clone https://github.com/ffgtso/gluon-v2015.1.git gluon-2015.1-ffgt
    mkdir gluon-2015.1-ffgt/site
    rsync -av --progress site-ffgt-v2015.1/ gluon-2015.1-ffgt/site/
else
    (cd gluon-2015.1-ffgt ; git pull)
fi

if [ ! -e baserelease.txt ]; then
    echo "0.7.0+0" >baserelease.txt
fi

    touch images/factory/ffgt-firmware-buildinfo-${RELEASE}

    echo "Buildslave: ${NODE_NAME}" >>images/factory/ffgt-firmware-buildinfo-${RELEASE}
    echo "Buildjob: ${JOB_URL}" >>images/factory/ffgt-firmware-buildinfo-${RELEASE}
fi

This assumes that each repo is checked out separately (by Jenkins) at job's root, obviously.
