-# This configuration was automatically generated from a CircleCI 1.0 config.
-# It should include any build commands you had along with commands that CircleCI
-# inferred from your project structure. We strongly recommend you read all the
-# comments in this file to understand the structure of CircleCI 2.0, as the idiom
-# for configuration has changed substantially in 2.0 to allow arbitrary jobs rather
-# than the prescribed lifecycle of 1.0. In general, we recommend using this generated
-# configuration as a reference rather than using it in production, though in most
-# cases it should duplicate the execution of your original 1.0 config.
