#
# Quick summary:
#  - update debian/changelog using interactive utility "dch -i"
#    (you must have formatted the debian/changelog file according to Debian/Ubuntu strict rules!!)
#  - make deb
#  - run dput to upload to your PPA
#
# Note: debian control files must live in the root folder of the project, not inside "collector" or "tools"
