## About

Twiggy is a code size profiler for Wasm. It analyzes a binary's call graph to

answer questions like:

* Why was this function included in the binary in the first place? Who calls it?

* What is the *retained size* of this function? I.e. how much space would be

  saved if I removed it and all the functions that become dead code after its

  removal.

Use Twiggy to make your binaries slim!

## Install Twiggy

Ensure that you have [the Rust toolchain installed](https://www.rust-lang.org/),

then run:

```

cargo install twiggy

```
