Writing libraries for common code is definitely reasonable. I'm not too
big a fan of another wrapper layer, though (the Tw.* objects are really
just a wrapper for the C++ code). I don't think that this would make
BTW: In my opinion, there shouldn't be any major API changes, as we're
heading towards a stable release. Minor things, maybe (like the read
function), but nothing major.

As long as your archive doesn't get too large, I'd keep it in one file.
Or separate it on a functionality level, at most (e.g., bundle all
file-related functions in one file, all GUI-related functions in
another). But having a hundred files to maintain is no easy task ;).

Yeah, such a flag should definitely come. Ideally, it should come on a
per-script basis, though, in addition to the global ones. I'm not sure
if this will come until the release, though.

Unfortunately, I have no notes yet. Some ideas, yes, but no notes. I'm
currently working on updating Alain's manual. After that, I'll look into
a scripting manual. But ask whatever you want to know (I'll try to find
an answer ;)).

Sure (though whether I'm knowledgeable, I don't know ;))

Of course you can do that. However, I don't think there are many Tw
script authors out there, yet, and those who are would probably
appreciate correct information ;). So it might be better to check things
before publishing them.

Well, my intention is to whip up some stuff from the C++ POV. What is
and isn't available, what can and can't be done, what should and
shouldn't be done. Beyond that, I'll definitely ask you (or whoever has
some experience with scripting and is willing to help) if you can
contribute some stuff. Like common pitfalls, how to avoid them,
important workarounds, etc.
