+/// Simple WASI executor, adapted from the NodeJS WASI module API docs [1].
+///
+/// Usage: wasi-node <command> [<args> .. ]
+///
+/// Environment variables:
+///
+/// WASI_NODE_PREOPENS - optional JSON file defining the application sandbox
+/// directory structure. See [1] for details.
+///
+/// WASI_NODE_ENV - optional JSON file defining the application environment.
+/// If omitted then the process's POSIX environment is used; this may leak
+/// information. If a clean environment is required then set this to /dev/null
+/// or some other empty file.
+///
+/// [1] https://nodejs.org/api/wasi.html
