I've been looking for this. Tcl apps are hard to run today when you're not a dev. Like the wonderful Grimm dictionary compiled into a TCL app ages ago by a German Uni.
Way back in the days, I always thought that Tcl/Tk had a pretty good packaging story compared to the P-languages, given the presence of Starkits-/packs[1], and (somewhat sadly) the absence of dependencies.
I think they still exist in theory. The last time I tried one it crashed. The original TCLKit developer has not maintained it for years, but it is still around.
