+Boolean Objects
+---------------
+
+Booleans in Python are implemented as a subclass of integers.  There are only
+two booleans, :const:`Py_False` and :const:`Py_True`.  As such, the normal
+creation and deletion functions don't apply to booleans.  The following macros
+are available, however.
+
+
+.. cfunction:: int PyBool_Check(PyObject *o)
+
+   Return true if *o* is of type :cdata:`PyBool_Type`.
+
+
+.. cvar:: PyObject* Py_False
+
+   The Python ``False`` object.  This object has no methods.  It needs to be
+   treated just like any other object with respect to reference counts.
+
+
+.. cvar:: PyObject* Py_True
+
+   The Python ``True`` object.  This object has no methods.  It needs to be treated
+   just like any other object with respect to reference counts.
+
+
+.. cmacro:: Py_RETURN_FALSE
+
+   Return :const:`Py_False` from a function, properly incrementing its reference
+   count.
+
+
+.. cmacro:: Py_RETURN_TRUE
+
+   Return :const:`Py_True` from a function, properly incrementing its reference
+   count.
+
+
+.. cfunction:: PyObject* PyBool_FromLong(long v)
+
+   Return a new reference to :const:`Py_True` or :const:`Py_False` depending on the
+   truth value of *v*.
