I realized reading furhter messages what was the
problem: deficiency of Unix to identify module path.

Here's a few findings: on Linux readlink of /proc/self/exe
and probably dladdr on Mac as well.

(Note, geniuses at Qt "assume that argv[0] contains the file name of the 
executable (which it normally does)." Yeah, right!)

On Mac drag-and-drop, I don't think .app to drag, but the
(jsoftware/)j602 folder, which will have the .app, like
many programs do even in Application folder such as Office,
Adobe etc.

I agree about headless shells, but then you aren't
a novice use either shy from tar.
