+     "Package chanqueue implements a queue that uses channels for input and
+output to provide concurrent access to a re-sizable queue.  This allows the
+queue to be used like a channel.  Closing the input channel closes the output
+channel when all queued items are read, consistent with channel behavior.  In
+other words chanqueue is a dynamically buffered channel with up to infinite
+capacity.")
