less
+than 50 bytes, and useful for many general cases with less than 300 bytes.
+@item Incremental, bounded CPU use.  It can be used to chew on input data in
+arbitrarily tiny bites.  This is a useful property in hard real-time 
environments.
+@item Can use either static or dynamic memory allocation.
