> For a longer explanation, these two points mean that `wasm-gc` is likely no

> longer a useful command to run for you:

>

> 1. The Rust compiler now natively supports `--gc-sections` when linking wasm

>    executables, which means wasm executables already have 90% of their garbage

>    removed when coming out of the compiler.

> 2. The `wasm-pack` (and `wasm-bindgen`) project will already run this by

>    default for you, so there's no need to run it again.

> Don't include this build! If you think you need to feel free to open an issue

> on `wasm-pack` or `wasm-bindgen`, as it may be a bug in one of those projects!

A small command to gc a wasm module and remove all unneeded exports, imports,

functions, etc. This is effectively `--gc-sections` for arbitrary wasm

executables. Not needed by Rust programs coming out of the Rust compiler, only

provided here nowadays for learning purposes and to be used as a library if

necessary.
