+and services as raw streams of text, Nu looks at each input as something with
+structure.  For example, when you list the contents of a directory, what you
+get back is a table of rows, where each row represents an item in that
+directory.  These values can be piped through a series of steps, in a series
+of commands called a ``pipeline''.")
