+# This script creates a list of data types where each type is followed
+# by the C++ mangled name for that type. That list is then compared
+# against the list in the c++-types.data file for the platform being
+# checked. Any difference between the two would mean that the C++ ABI
+# had changed and that should not happen even if the change is compatible
+# at the C language level.
