cpsenize is a tiny Node.js utility that converts ordinary synchronous functions into “callback‑passing style” (CPS) functions. By wrapping a function, it automatically forwards its return value (or any thrown error when enabled) to a final `(err, result)` callback, making synchronous code easier to use in asynchronous or mixed‑style workflows. It’s aimed at JavaScript developers who want a lightweight way to integrate legacy or simple pure functions into CPS‑oriented codebases.
