        This depends on the structure of the application or tool.
        If it's an iOS application, it's a bundle where we have:
            /...../wanted-dir/AppName.app/executable
            (2 levels up, wanted-dir is a randomized serial number at some path)
        If it's built as a Mac OS X application bundle we have:
            /...../wanted-dir/AppName.app/Contents/MacOS/executable
            (4 levels up, typically wanted-dir is /Applications if installed, but doesn't have to be)
        If it's built as a simple Unix-y tool we have:
            /...../wanted-dir/executable
            (1 level up, wanted-dir is wherever the tool has been placed)
