Uli,

The instructions you're looking for cannot be found. (At least I've
never been able to find them, looking on and off since 2004.)

It's been a while since I played with the program but if you're
patient and play with the import/export feature and the .txt files it
uses, you can gain some insight into how it works.

I wish LX would devote a few more hours to rounding out the
functionality of that program. It seems it was dropped on the floor
about 15% short of being where it was intended.

Not that I've ever done that myself
