# Xcode runs dsymutil to make the final dSYM file it will still find the debug info
# for the object file that provided the original _main. This back-reference has the
# interesting side-effect of the debug information still referring to the original
# 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.
