Well, because MLCad's process is so manual, it is very easy to create MPD files
that are incomplete or not in the right order.
One of MPD's rules is that the first FILE is the top level model. I've gotten
plenty of letters from people who say they take the MPD file they created in
MLCad into LPub and it deosn't do the right thing. Typically because they have
not had the top level file as the first FILE.
Once you've got LPub installed, you simply open the top level file, and LPub
will traverse the entire model determining all the user defined files involved
in the model automatically.
Then you use the "Save As MPD" menu and it will write out the file as a complete
MPD and the files are in order of appearance.
Two menu item clicks and you've got an MPD file. MLCad's process is certainly
harder than LPub's.
Maybe we're not talking the same "easy vs hard" processes?!?

I agree totally.
There is a specification on LDraw.org that defines MPD file format. Maybe you
could simply provide a parenthetical link to that document for format specifics.
Then jump into LPub and MLCad ways of doing it.
