+//! Unsafe, platform specific bindings to dynamic library loading facilities.
+//!
+//! These modules expose more extensive, powerful, less principled bindings to the dynamic
+//! library loading facilities. Use of these bindings come at the cost of less (in most cases,
+//! none at all) safety guarantees, which are provided by the top-level bindings.
+//!
+//! # Examples
+//!
+//! Using these modules will likely involve conditional compilation:
+//!
+//! ```ignore
+//! # extern crate libloading;
+//! #[cfg(unix)]
+//! use libloading::os::unix::*;
+//! #[cfg(windows)]
+//! use libloading::os::windows::*;
+//! ```
+
+macro_rules! unix {
+    ($item: item) => {
+        /// UNIX implementation of dynamic library loading.
+        ///
+        /// This module should be expanded with more UNIX-specific functionality in the future.
+        $item
+    }
+}
+
+macro_rules! windows {
+    ($item: item) => {
+        /// Windows implementation of dynamic library loading.
+        ///
+        /// This module should be expanded with more Windows-specific functionality in the future.
+        $item
+    }
