+This is the `wasmtime-environ` crate, which contains the implementations
+of the `ModuleEnvironment` and `FuncEnvironment` traits from
+[`cranelift-wasm`](https://crates.io/crates/cranelift-wasm). They effectively
+implement an ABI for basic wasm compilation, which can be used for JITing,
+native object files, or other purposes.
