+|* Many exotic languages can interoperate with C code but have a harder time  *|
+|* with C++ due to name mangling. So in addition to C, this interface enables *|
+|* tools written in such languages.                                           *|

+|* Note: This interface is experimental. It is *NOT* stable, and may be       *|
