Wish.app is used to invoke the tk UI stuff: https://discussions.apple.com/thread/3602966?start=0&tstart=0

Windows also uses wish.exe.

Subject: [PD] OSX Bundle inside OSX Bundle


Hi OSX afficionados,

In the Pd-extended app bundle for OSX, why does wish start the pd binary, while on Debian it is the pd binary which starts wish?

Related question-- if I have a gui toolkit named gui.app, is it possible to just shove it into pd-gui-port.app/Content/Resources, and then 
open it from s_inter.c?

Thanks,
Jonathan
