+# This file lists reviewers that are auto-assigned when a pull request modifies

+# The GitHub "code owners" mechanism is used exclusively to auto-assign

+# to receive an approval from a "code owner" in particular -- any LLVM project
+# member can approve pull requests.
+#
+# Note that GitHub's concept of "code owner" is independent from LLVM's own
+# "code owner" concept, they merely happen to share terminology. See
+# https://llvm.org/docs/DeveloperPolicy.html#code-owners, as well as the
+# CODE_OWNERS.txt files in the respective subproject directories.
