One more thing: I will use CAMERA.dat and LOOK_AT.dat in each Frame file in my
planned LDA (hopefully LDA2005...). I find them very handy, anyone can use them
and move them around in MLCad or whatever LDraw editor. This is how I made them,
but anyone can make his own version of them:

A sample frame may look like this:

and the animation program will generate this line in the L3P batch file:

"l3p -o testing.ldr -ca60 -cc100,-150,0 -cla20,-50,40"

Sad thing that Lars doesn't want to add support for these things directly in
L3P...! But on the other hand, I plan to make LDA meta-commands that sets light
attributes and maybe more, so I'll likely need this preprocessing anyway.

(...) Unfortunately, I am very busy right now. Once again, I have to move and it sure takes its toll from my resources.
