// 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
