 Usage:
-  ruby bench.rb (c|ruby|dump) (null|text|tokens|count|statistic|yaml|html) [SIZE in KB] [stream]
+  ruby bench.rb (c|ruby|dump) (null|text|tokens|count|statistic|yaml|html) [size in kB] [stream]
 
-  SIZE defaults to 100.
+  SIZE defaults to 100 kB (= 100,000 bytes).
   SIZE = 0 means the whole input.
   SIZE is ignored when dump is input.
