-# autoupdater
-# ====
-#
-# This script prints the name of the autoupdater branch depending on the build
-# configuration. Its output is suitable for use as the GLUON_BRANCH build
-# variable of gluon.
-#
-# The idea is to take whatever comes in the GLUON_BRANCH build variable,
-# except when this value is not one of the well-known branch names; then fall
-# back to 'nightly'.
