+//! ## WebAssembly support
+//! 
+//! We use a third-party crate [`wasmparser`](https://crates.io/crates/wasmparser)
+//! created by Bytecode Alliance for parsing WebAssembly.
+//! It is a robust and high-quality parser, but its dependencies contain some `unsafe` code.
+//! We have manually audited it and found it to be sound.
+//! 
+//! Still, the security guarantees for it are not as ironclad as for other parsers.
+//! Because of that WebAssembly support is gated behind the optional `wasm` feature.

+//! the `wasm` feature if you want to parse WebAssembly.
