-# Lists some code owners.

-# A codeowner just oversees some part of the codebase. If an owned file is changed then the
-# corresponding codeowner receives a review request. An approval of the codeowner might be
-# required for merging a PR (depends on repository settings).
-#
-# For details about syntax, see:
-# https://help.github.com/en/articles/about-code-owners
-# But here are some important notes:
-#
-# - Glob syntax is git-like, e.g. `/core` means the core directory in the root, unlike `core`
-#   which can be everywhere.
-# - Multiple owners are supported.
-# - Either handle (e.g, @github_user or @github_org/team) or email can be used. Keep in mind,
-#   that handles might work better because they are more recognizable on GitHub,
-#   you can use them for mentioning unlike an email.
-# - The latest matching rule, if multiple, takes precedence.
