+# This script publishes the core of Scala to maven for use as locker downstream,
+# and saves the relevant properties used in its build artifacts, versions.properties.
+# (This means we'll use locker instead of quick downstream in dbuild.
+#  The only downside is that backend improvements don't improve compiler performance itself until they are in STARR).
+# The version is suffixed with "-${sha:0:7}-SNAPSHOT"
