| 7 # Script to push the barback package to pub. Barback is treated specially | |
| 8 # because it is tightly coupled to the SDK. Pub includes its own copy of | |
| 9 # barback but also includes code that is run against the user's copy of barback. | |
| 10 # To ensure that those are in sync, each version of the SDK has a single | |
| 11 # version of barback that it works with. | |
| 12 # | |
| 13 # We enforce this by placing a narrow SDK constraint in each version of barback. | |
| 14 # This ensures the only barback that will be selected is the one that works | |
| 15 # with the user's SDK. Once barback is more stable, we can loosen this. | |
| 16 # | |
| 17 # Usage: publish_barback.py | |
| 18 # | |
| 19 # "pub" must be in PATH. | |
