	vcompile - virtual compiling of rooms

DESCRIPTION
	vcompile allows for objects without an actual file matching the
	objects filename.
	
	When the driver is instructed to load a file, it first check if it is
	already loaded. If not it looks in the specified dir. If there is
	no file there that can be used, it looks for a file named vcompile.c
	in the dir (and in the parent dirs!). If found, that object is loaded
	and the function compile_virtual in it is called with the file name
	as argument. This function should clone an object and return it.

	If anything else than an object is returned, you will get the usual
	error message about trying to load a non-existing object.

	The driver now changes file name on the clone to the file name given
	as argument to compile_virtual, and the reset function in the object
	is called with argument -1 .

EXAMPLE
	Take a careful look at /doc/vcompile.c .
	Try a 'goto' to any file in that dir.

NOTE
	Without great care, a map area is about the most boring area there is
	in the game.

	Be sure your vcompile.c cannot be shadowed.

	Be sure that your don't accept every file name in compile_virtual.
	You should check for the files '.acl', '..' and '.', at least.
