-=== Summary ===
+=== Introduction ===
 The client has several ways of writing messages to the server, each of which has different behaviour with respect to synchronization and reply processing.  The user must specify the way these functions operate by passing them data structures and functions which will be called on the data returned from the server.  This is analogous to the "reduce" or "foldl" functions found in Clojure and Scheme respectively.  If you are unfamiliar with using functions as arguments, then it may be worthwhile to experiment with in the REPL with either "map" or "reduce".  For example,  
+
+{{{
+user=> (map inc [1 2 3 4 5])
+(2 3 4 5 6)
+user=> (map (fn [e] (* e 2)) [1 2 3 4 5]) ; an anonymous function
+(2 4 6 8 10)
+user=> (map #(* % 2) [1 2 3 4 5]) ; same, but with alternative syntax        
+(2 4 6 8 10)
+user=> ((juxt inc dec) 1)          
+[2 0]
+}}}
+
+The client behaviour more closely corresponds to the "reduce" function.
