 Until now, Rust's WebAssembly support has had two main options, the
 Emscripten-based option, and the wasm32-unknown-unknown option. The latter
 option is lighter-weight, but only supports `no_std`. WASI enables a new
-wasm32-unknown-wasi target, which is similar to wasm32-unknown-unknown in

 that it doesn't depend on Emscripten, but it can use WASI to provide a
 decent subset of libstd.
