//! # Feature Flags
//!
//! <table>
//! <tr><th>Feature
//!     <th>Description
//! <tr><td><code>alloc (default)</code>
//!     <td>Enable features that require use of the heap, RSA in particular.
//! <tr><td><code>std</code>
//!     <td>Enable features that use libstd, in particular
//!         <code>std::error::Error</code> integration. Implies `alloc`.
//! <tr><td><code>wasm32_unknown_unknown_js</code>
//!     <td>When this feature is enabled, for the wasm32-unknown-unknown target,
//!         Web APIs will be used to implement features like `ring::rand` that
//!         require an operating environment of some kind. This has no effect
//!         for any other target. This enables the `getrandom` crate's `js`
//!         feature.
//! </table>

// When running mk/package.sh, don't actually build any code.
