Select which executable inside an AppImage to run based on argv[0]?

Many executables use the name under which they are invoked (argv[0]) to select one of multiple different roles they can fulfill - like "xz" which, if invoked as "xzcat" or "unxz" performs different operations.

It would make a lot of sense for AppImage files to allow for this, such that multiple executables inside the AppImage can all be executed by just creating differently named soft-links to the AppImage file.

I use this method in my https://github.com/lvml/makeaoi tool to allow packing multiple executables into the same directory - so their dependencies can be shared. (Think of examples like packaging "ffmpeg" and "ffprobe" into the same directory. Or "kdenlive" and its "kdenlive_render" batch processing tool.)

It would be great if AppImage would support this by also using the name it was invoked with to use names other than "AppRun" to run (if a file or link of that name exists).
