# Note that we're not making use of the matrix expansion that Travis provides -
# it doesn't work very well for our collection of builds that each require a
# combination of environment variables and packages that need to be defined
# per-job in the jobs.include list. Jobs defined in the include key don't
# modify or extend job specifications from the matrix, and actually add a whole
# new job to the matrix (!), so using the matrix would leave us with a
# subset of jobs being under-specified.
# To get around this, we're using YAML anchors and aliases to avoid repeating
# config across different builds.

# The following keys prefixed with an underscore are not directly interpreted by
# Travis, and are used to provide a centralised config store for config that
# gets referenced inside the jobs.include map.
# The apt addon can take nested lists in its subkeys (and flattens them), so we
# use that to our advantage to merge a list of generic packages with a list of
# job-specific packages in YAML.
