Great, thanks for this.

I built webkit without opening VS. However I wish to step through the
code using VS. What I don't understand is that using debug-safari
doesn't allow me to step through the code using VS because it launches
a new instance of VS which only lists the executable file. This
brings me back to my original question of why use debug-safari? Or
perhaps I could rephrase it as "how do I step through code by using
debug-safari?" I can step through code, but only by NOT using
