the big trick that might help (and that isn't quite spelled out
explicitly on that page) is to wrap your C/C++ activity in a
combination of shell script (which sets up some environment
variables, based on the standard sugar args, i.e., --bundle-id,
--activity-id, etc) and a pre-load shared library that contrives
to get those values into the X properties where they need to go.
