-"""Script to pull chromium.perf stats from chrome-infra-stats API.
-
-Currently this just pulls success rates from the API, averages daily per
-builder, and outputs a CSV. It could be improved to provide more detailed
-success rates or build times.
-
-The API documentation for chrome-infra-stats is at:
-https://apis-explorer.appspot.com/apis-explorer/?
