+    (description "@code{core.cache} is a Clojure contrib library providing the
+following features:
+
+An underlying CacheProtocol used as the base abstraction for implementing new
+synchronous caches
+
+A defcache macro for hooking your CacheProtocol implementations into the
+Clojure associative data capabilities.
+
+Implementations of some basic caching strategies
+
+First-in-first-out (FIFOCache)
+Least-recently-used (LRUCache)
+Least-used (LUCache -- sometimes called Least Frequently Used)
+Time-to-live (TTLCacheQ)
+Naive cache (BasicCache)
+Naive cache backed with soft references (SoftCache)
+
+Implementation of an efficient buffer replacement policy based on the low
+inter-reference recency set algorithm (LIRSCache) described in the LIRS paper
+
+Factory functions for each existing cache type
+
+Caches are generally immutable and should be used in conjunction with
+Clojure's state management, such as atom.  SoftCache is the exception here,
+built on top of mutable Java collections, but it can be treated as an
+immutable cache as well.
+
+The @code{clojure.core.cache} namespace contains the immutable caches
+themselves.  The @code{clojure.core.cache.wrapped} namespace contains the same
+API operating on caches wrapped in atoms, which is the \"normal\" use in the
+wild.")
