+//! CH Utilities - Macro Rules

+//! Provides convenient macros for developing the game CH

+#![deny(missing_docs)]
+
+/// Import modules and re-export all of their public items.
+///
+/// This macro declares modules with `mod $module;` and then re-exports
+/// everything from them with `pub use $module::*;`, making the items of the
+/// modules available as if they were defined in the current scope.
+///
+/// Supports both single and multiple module imports:
+///
+/// # Examples
+///
+/// ```
+/// import!(my_module);
+/// import!(foo, bar, zsq);
+/// ```
