        # symbol name, so stack-traces will show both our wrapper main and the original
        # user main as 'main', and adding a symbolic breakpoint for 'main' will break on
        # both functions. Although a bit weird, it's a good thing, as the user will still be
        # able to add symbolic breakpoints for 'main', not caring that the symbol is actually
        # called 'qt_main' now.
