In what sense? Code running the runtime package can just print it. Or if you run the program under gdb, you should be able to "print 'runtime.g'" (you need the quotes because otherwise gdb will think it is a structure field reference). At least, gdb works that way on GNU/Linux, not sure about your operating system.
