+       "FLOW is a flowchart graph library.  Unlike other graphing libraries,
+this one focuses on nodes in a graph having distinct @code{ports} through which
+connections to other nodes are formed.  This helps in many concrete scenarios
+where it is important to distinguish not only which nodes are connected, but
+also how they are connected to each other.
+
+Particularly, a lot of data flow and exchange problems can be reduced to such
+a @code{flowchart}.  For example, an audio processing library may present its
+pipeline as a flowchart of segments that communicate with each other through
+audio sample buffers.  Flow gives a convenient view onto this kind of problem,
+and even allows the generic visualisation of graphs in this format.")
