+
+[`json-parse-better-errors`](https://github.com/zkat/json-parse-better-errors) is a Node.js library for managing
+local key and content address caches. It's really fast, really good at
+concurrency, and it will never give you corrupted data, even if cache files
+get corrupted or manipulated.
+
+It was originally written to be used as [npm](https://npm.im)'s local cache, but
+can just as easily be used on its own
+
