Pub is currently dogfooding the new Dart async/await syntax. Since the Dart VM doesn't natively support it yet, we are using the async-await compiler package.

We run that to compile pub-using-await from sdk/lib/_internal/pub down to vanilla Dart code which is what you see here. To interoperate more easily with the rest of the repositry, we check in that generated code.

When bug #104 is fixed, we can remove this entirely.

The code here was compiled using the async-await compiler at commit:
