+// _tokio_codec are the items that belong in the `tokio_codec` crate. However,
+// because we need to maintain backward compatibility until the next major
+// breaking change, they are defined here. When the next breaking change comes,
+// they should be moved to the
+// `tokio_codec` crate and become independent.
+//
+// The primary reason we can't move these to `tokio-codec` now is because,
+// again for backward compatibility reasons, we need to keep `Decoder` and
+// `Encoder` in tokio_io::codec. And `Decoder` and `Encoder` needs to reference
+// `Framed`. So they all still need
+// to still be in the same module.
