I think I mean... I don't remember!

Maybe, but that's not really the problem to me.

... but the problem with *not* having all code in the same file (as in L3P
output files) is having to hunt down all the include files!

I'd say let's start with camera.dat and lookat.dat. If we make them with lines
only (linetype 2 and maybe some edge primitives), they will become invisible in
the POV pics!

This is quite exactly my vision too, you just use different words!
Working with keyframes and automatic tweening would be fantastic, but I have no
clue on how to make that yet. Maybe we can find something interesting by
studying LSynth? The problem with filling hoses is kind of reminds me of
tweening...
Anyway, first I will debug LDA2001, and then I'll think about the what the next
step will be.
