SwigPyBuiltin_SetMetaType. For %import statements, move the runtime import out of SWIG_init and into the .py file. The reason for this is that the import must be executed within the python execution frame of the module, which is true in the .py file, but *not* true in the initialization function. Had to re-order the .py file slightly to put the 'import' statements at the top; that's necessary to make sure base types from an imported module are initialized first. If -builtin isn't used, then the .py code is not re-ordered. Added an explanation and workaround for the limitation that wrapped types are not raise-able. git-svn-id: https://swig.svn.sourceforge.net/svnroot/swig/branches/szager-python-builtin@12585 626c5289-ae23-0410-ae9c-e8d60b6d4f22
