 #![forbid(unsafe_code)]
 
+// Cargo.toml cannot have self-referential dependencies, so you can't just
+// specify the actual serde crate when you define a feature called serde. We
+// instead call the serde crate as serde_crate and then rename the crate to
+// serde, to get around this in an intuitive manner.
 #[cfg(feature = "serde")]
 extern crate serde_crate as serde;
