+// This file was borrowed from the SWIG project to allow use to 
+// wrap PMTs that use intrusive pointers. This is only necessary
+// to support backwards compatability with older distributions of
+// Linux that do not natively support a new enough version of SWIG.
+// We do this to prevent having to update our dependency on a new
+// SWIG. Eventually, the need for this should go away.
+
+// Allow for different namespaces for shared_ptr / intrusive_ptr - they could be boost or std or std::tr1
+// For example for std::tr1, use:
+// #define SWIG_SHARED_PTR_NAMESPACE std
+// #define SWIG_SHARED_PTR_SUBNAMESPACE tr1
+// #define SWIG_INTRUSIVE_PTR_NAMESPACE boost
+// #define SWIG_INTRUSIVE_PTR_SUBNAMESPACE
