# We will need some packages to execute this locally:
# sudo apt-get install build-essential autoconf automake autotools-dev dh-make debhelper devscripts fakeroot xutils lintian pbuilder cdbs
#
# To make this script work also the Qt 5.6 Trusty repository has to be in place
# https://launchpad.net/~beineri/+archive/ubuntu/opt-qt56-trusty

# sudo apt-add-repository ppa:beineri/opt-qt56-trusty
# sudo apt-get update
#
# The GPG public key $GPG_PUBLIC_KEY also has to be in place locally
# Also a ~/.dput.cf has to be in place
