+	<longdescription>
+		The @concurrent-extra@ package offers among other things the
+		following selection of synchronisation primitives:
+		
+		* @Broadcast@: Wake multiple threads by broadcasting a value.
+		
+		* @Event@: Wake multiple threads by signalling an event.
+		
+		* @Lock@: Enforce exclusive access to a resource. Also known as a
+		binary semaphore or mutex. The package additionally provides an
+		alternative that works in the @STM@ monad.
+		
+		* @RLock@: A lock which can be acquired multiple times by the same
+		thread. Also known as a reentrant mutex.
+		
+		* @ReadWriteLock@: Multiple-reader, single-writer locks. Used to
+		protect shared resources which may be concurrently read, but only
+		sequentially written.
+		
+		* @ReadWriteVar@: Concurrent read, sequential write variables.
+		
+		Please consult the API documentation of the individual modules for
+		more detailed information.
+		
+		This package was inspired by the concurrency libraries of Java and
+		Python.
