Yes, it has been discussed and the conclusion of this discussion was to
go ahead as proposed.

Indeed, the module directory should be added to mtree, I'll add that.
It is versioned.

you mean /bin instead of /usr/bin? I am not sure here.  I tend to say
no, Lua should be used embedded in C programs imo and not as a language
for general commands.  But that is only my opinion, I am open.

I'll check this.

different story.

All under external/mit/lua would be in the tarball, including the
Makefiles, I think that is not so practical.
