+ * ============= wasm-optimize util =============
+ *
+ * == What is this?
+ *
+ * This file allows to optimize a WebAssembly binary file (`.wasm`) by running
+ * binaryen's wasm-opt tool on it, through its JavaScript API.
+ *
+ * To run it, provide the source WebAssembly file as first argument and the
+ * output as second:
+ * ```
+ * node wasm-optimize.mjs source.wasm dest.wasm
+ * ```
+ *
+ * == Why?
+ *
+ * As the WebAssembly file produced by the RxPlayer is mostly for performance
+ * enhancement, it is important that we squeeze the most performance out of it
+ * at compile-time.
+ *
+ * The wasm-opt tool specically optimizes WebAssembly files, it is different
+ * from performance improvements made by the initial source compiler (e.g. the
+ * Rust compiler) which may not have the same constraints. Whether this script
+ * brings or not an improvement in comparison to the source WebAssembly file
+ * still should probably be regularly checked in real-life scenarios.

-  1. Install [cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html),

-  2. Install [binaryen](https://github.com/WebAssembly/binaryen), which is a

+To do this, the easiest way would be to rely on `rustup`, a tool to install and
