+//! This module provides a function to render a Move abort status string into a more human-readable
+//! error message using the clever error rendering logic.
+//!
+//! The logic in this file is largely a stop-gap to provide Clever Error rendering in the CLI while
+//! it still uses the JSON-RPC API. The new GraphQL API already renderd Clever Errors on the server
+//! side in a much more robust and efficient way.
+//!
+//! Once the CLI is updated to use the GraphQL API, this file can be removed, and the GraphQL-based
+//! rendering logic for Clever Errors should be used instead.
