New Revision: 151271
URL: http://llvm.org/viewvc/llvm-project?rev=151271&view=rev
Log:
typemaps to allow Python to invoke the new SBModule::GetVersion() API. Memory management is taken care of automatically so that Python users can simply say my_list = my_module.GetVersion() and receive a new list with the version numbers, if any, inside.
