+# Explicitly ban select functions from being used in gRPC.
+#
+# Any new instance of a deprecated function being used in the code will be
+# flagged by the script. If there is a new instance of a deprecated function in
+# a Pull Request, then the Sanity tests will fail for the Pull Request.
+# We are currently working on clearing out the usage of deprecated functions in
+# the entire gRPC code base.
+# While our cleaning is in progress we have a temporary allow list. The allow
+# list has a list of files where clean up of deprecated functions is pending.
+# As we clean up the deprecated function from files, we will remove them from
+# the allow list.
+# It would be wise to do the file clean up and the altering of the allow list
+# in the same PR. This will make sure that any roll back of a clean up PR will
+# also alter the allow list and avoid build failures.
