+//! System bindings for the wasm/web platform
+//!
+//! This module contains the facade (aka platform-specific) implementations of
+//! OS level functionality for wasm. Note that this wasm is *not* the emscripten
+//! wasm, so we have no runtime here.
+//!
+//! This is all super highly experimental and not actually intended for
+//! wide/production use yet, it's still all in the experimental category. This
+//! will likely change over time.
+//!
+//! Currently all functions here are basically stubs that immediately return
+//! errors. The hope is that with a portability lint we can turn actually just
+//! remove all this and just omit parts of the standard library if we're
+//! compiling for wasm. That way it's a compile time error for something that's
+//! guaranteed to be a runtime error!
