+//! `wasmtime-wasi` now supports using multiple snapshots to interface to the
+//! same `WasiCtx`!
+//!
+//! `wasmtime_wasi::Wasi::new(&Store, WasiCtx)` is a struct which owns your
+//! `WasiCtx` and provides linkage to every available snapshot.
+//!
+//! Individual snapshots are available through
+//! `wasmtime_wasi::snapshots::preview_{0, 1}::Wasi::new(&Store, Rc<RefCell<WasiCtx>>)`.
