+      (description "Golang package for conveniently using named read/write
+locks.  These appear to be especially useful for synchronizing access to
+session based information in web applications.
+
+The common use case is to use the package level functions, which use a package
+level set of locks (safe to use from multiple goroutines
+simultaneously).  However, you may also create a new separate set of locks
+test.
+
+All locks are implemented with read-write mutexes.  To use them like a regular
+mutex, simply ignore the RLock/RUnlock functions.")
