+# Each line is a file pattern followed by one or more owners.

+# These owners will be the default owners for everything in
+# the repo. Unless a later match takes precedence,
+# @global-owner1 and @global-owner2 will be requested for
+# review when someone opens a pull request.

+# modifies JS files, only @js-owner and not the global
+# owner(s) will be requested for a review.

+# Teams can be specified as code owners as well. Teams should
