+ "Used to trace execution of OCaml/Lwt programs (such as Mirage
+unikernels) at the level of Lwt threads. The traces can be viewed using
+JavaScript or GTK viewers provided by mirage-trace-viewer or processed by
+tools supporting the Common Trace Format.
+When compiled against a normal version of Lwt, OCaml's cross-module inlining
+will optimise these calls away, meaning there should be no overhead in the
+non-profiling case.")
