Here's the function that I wrote to do something similar a couple days
ago. I pulled the code from redit.c in the save internally function. It's
all hackish and probably ugly, but the code works. I removed alot of
white space from the email in hopes that it will fall under the 200 line
limit. That'll make the code a bt harder to read.

Hope this helps.
PS: The reason I wrote this was so that my nexit command (you probably
called it 'dig') and duperoom (you probably called it 'copyto') would not
report "Room doesn't exist", but would just make the room and go on.
Now that I've looked at it, I think that a FREE(new_world) call is needed
at the bottom to prevent a mem-leak. I don't have one at anywhere in my
redit_save_iternally. Any comments from anyone?
