21description: """
22This library can be used to trace execution of OCaml/Lwt programs (such as
23Mirage unikernels) at the level of Lwt threads. The traces can be viewed using
24JavaScript or GTK viewers provided by [mirage-trace-viewer][] or processed by
25tools supporting the [Common Trace Format (CTF)][ctf]. Some example traces can
26be found in the blog post [Visualising an Asynchronous
27Monad](http://roscidus.com/blog/blog/2014/10/27/visualising-an-asynchronous-monad/).
28
29Libraries can use the functions mirage-profile provides to annotate the traces
30with extra information. When compiled against a normal version of Lwt,
31mirage-profile's functions are null-ops (or call the underlying untraced
32operation, as appropriate) and OCaml's cross-module inlining will optimise
33these calls away, meaning there should be no overhead in the non-profiling
34case.
