 The resulting `box' program is a Guile interpreter which has one
 additional data type called `box'.
 
+
+* The Box Data Type
+
 A box is simply an object for storing one other object in.  It can be
 used for passing parameters by reference, for example.  You simply
 store an object into a box, pass it to another procedure which can
 store a new object into it and thus return a value via the box.
 
+
+** Usage
+
 Box objects are created with `make-box', set with `box-set!' and
 examined with `box-ref'.  Note that these procedures are placed in a
 module called (box-module) and can thus only be accessed after using
 this module.  See the following example session for usage details:
