# Build the Debian packages using Docker images.

# This script builds the Docker images and then executes them sequentially, each
# one building a Debian package for the targeted operating system. It is
# designed to be a "single command" to produce all the images.
#
# By default, builds for all known distributions, but a list of distributions
# can be passed on the commandline for debugging.
