+// Web apps which integrate Surfer as an iframe can give commands to surfer via
+// the .postMessage [1] function on the iframe.
+//
+//  For example, to tell Surfer to load waveforms from a URL, use
+// `.postMessage({command: "LoadUrl", url: "https://app.surfer-project.org/picorv32.vcd"})`
+//
+//  For more complex functionality, one can also inject any `Message` defined
+// in `surfer::Message` in surfer/main.rs. However, the API of these messages
+// is not stable and may change at any time. If you add functionality via
+// these, make sure to test the new functionality when changing Surfer version.
