 - Asynchronous completion callbacks with exit statuses/reasons
 - Improved exception handling coverage (optional; increases build size)
 - Supports `PROXYFS` as well as `NODEFS` and `WORKERFS`, so you can chain operations between instances without needing to offload data
+- Can work with JavaScript or on behalf of other WebAssembly projects
 - Minimal build variants

 Ideally, all of these should be handled:
 
-- 7-Zip writes textual information and errors to `stdout` and `stderr` respectively, which are mapped to `print(text)` and `printErr(text)`.
+- 7-Zip writes textual information and errors to `stdout` and `stderr` respectively, which call `print(text)` and `printErr(text)` every time a line of text is flushed from the buffer.
 - If the Emscripten runtime terminates unexpectedly, `onAbort(reason)` should be called with an explanation.
 - When errors happen inside 7-Zip, usually `onExit(errorCode)` will be called with an error code other than `0`.
 - If the Emscripten runtime has trouble starting up, for example if the `.wasm` file cannot be downloaded or the browser does not support certain features, there is a chance that the call to `JS7z()` may throw an error.
