+// This is a small "shim" program which is used when wasm32 unit tests are run
+// in this repository. This program is intended to be run in node.js and will
+// load a wasm module into memory, instantiate it with a set of imports, and
+// then run it.
+//
+// There's a bunch of helper functions defined here in `imports.env`, but note
+// that most of them aren't actually needed to execute most programs. Many of
+// these are just intended for completeness or debugging. Hopefully over time
+// nothing here is needed for completeness.
