-# Script to push the barback package to pub. Barback is treated specially
-# because it is tightly coupled to the SDK. Pub includes its own copy of
-# barback but also includes code that is run against the user's copy of barback.
-# To ensure that those are in sync, each version of the SDK has a single
-# version of barback that it works with.
-#
-# We enforce this by placing a narrow SDK constraint in each version of barback.
-# This ensures the only barback that will be selected is the one that works
-# with the user's SDK. Once barback is more stable, we can loosen this.
-#
-# Usage: publish_barback.py
-#
-# "pub" must be in PATH.
