+# 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.
