+\subsubsection{Boolean Objects \label{boolObjects}}
+
+Booleans in Python are implemented as a subclass of integers.  There
+are only two booleans, \constant{Py_False} and \constant{Py_True}.  As
+such, the normal creation and deletion functions don't apply to
+booleans.  The following macros are available, however.
+
+\begin{cfuncdesc}{int}{PyBool_Check}{PyObject* o}
+  Returns true if \var{o} is of type \cdata{PyBool_Type}.
+  \versionadded{2.3}
+\end{cfuncdesc}
+
+\begin{cvardesc}{PyObject*}{Py_False}
+  The Python \code{False} object.  This object has no methods.  It needs to
+  be treated just like any other object with respect to reference counts.
+\end{cvardesc}
+
+\begin{cvardesc}{PyObject*}{Py_True}
+  The Python \code{True} object.  This object has no methods.  It needs to
+  be treated just like any other object with respect to reference counts.
+\end{cvardesc}

+\begin{cfuncdesc}{int}{PyBool_FromLong}{long v}
+Returns \constant{Py_True} or \constant{Py_False} depending on the
+truth value of \var{v}.
