As you know, the mission files are in text (ASCII) format, which means that a mission could be created from start to finish using a text editor or generator. It is just a matter of knowing what lines to add in, and where. That is a known fact, having copied and pasted mission files using Notepad before.
Observing many folks flopping and floundering piteously, in their attempts to create missions, maybe an automatic generator would be a good thing.
Of course, as I said, I have not a clue how to put such a generator together,
