# can be also overridden by setting environment variables before sourcing this file. We
# don't support this for variables that change between branches and versions, e.g.
# version numbers because it creates a "sticky config variable" problem where an old
# value stays in effect when switching between branches or rebasing until the developer
# opens a new shell. We also do not support overriding of some variables that are
# computed based on the values of other variables.
#
# This file must be kept compatible with bash options "set -euo pipefail". Those options
# will be set by other scripts before sourcing this file. Those options are not set in
# this script because scripts outside this repository may need to be updated and that
