Hello.
When started from the GUI (Dock, Finder, open), the launcher adds a -psn_hi_low option where hi and low are numbers (hi usually 0) that form the process serial number. Not sure what it is used for. If however you pass any argument to the program, like:
% open -a Emacs --args -Q
no -psn-option is passed.
In Emacs it acts like a "started from GUI"-detector.
