`cl-pcg` is a [permuted congruential generator][pcg] implementation in pure
Common Lisp.
+Permuted congruential generators are seedable, small, fast,
+fairly-hard-to-predict random number generators. They can be useful for things
+like games. They can also be advanced and rewound efficiently.
+
PCGs are **not** cryptographically secure. If you need that, look elsewhere.
