# NOTE:
# This assumes you have a user `builder` and a folder `/home/builder/packages`.
# it will clone FreeCAD there and start pbuilder using pdebuild.
# For me this works using debian sid. (stretch/buster will probably not work!)
#
# After the build has finished, it will import the packes into a reprepro
# which is setup at /srv/repo
#
# So before using this script, you probably want to remove certain steps
# and change the paths, according to your setup.
