+
+		dmm_suite version 1.0
+			Released January 30th, 2011.
+
+		NOTE: Map saving functionality removed
+
+		defines the object /dmm_suite
+			- Provides the proc load_map()
+				- Loads the specified map file onto the specified z-level.
+			- provides the proc write_map()
+				- Returns a text string of the map in dmm format
+					ready for output to a file.
+			- provides the proc save_map()
+				- Returns a .dmm file if map is saved
+				- Returns FALSE if map fails to save
+
+		The dmm_suite provides saving and loading of map files in BYOND's native DMM map
+		format. It approximates the map saving and loading processes of the Dream Maker
+		and Dream Seeker programs so as to allow editing, saving, and loading of maps at
+		runtime.
+
+		------------------------
+
+		To save a map at runtime, create an instance of /dmm_suite, and then call
+		write_map(), which accepts three arguments:
+			- A turf representing one corner of a three dimensional grid (Required).
+			- Another turf representing the other corner of the same grid (Required).
+			- Any, or a combination, of several bit flags (Optional, see documentation).
+
+		The order in which the turfs are supplied does not matter, the /dmm_writer will
+		determine the grid containing both, in much the same way as DM's block() function.
+		write_map() will then return a string representing the saved map in dmm format;
+		this string can then be saved to a file, or used for any other purose.
+
+		------------------------
+
+		To load a map at runtime, create an instance of /dmm_suite, and then call load_map(),
+		which accepts two arguments:
+			- A .dmm file to load (Required).
+			- A number representing the z-level on which to start loading the map (Optional).
+
+		The /dmm_suite will load the map file starting on the specified z-level. If no
+		z-level	was specified, world.maxz will be increased so as to fit the map. Note
+		that if you wish to load a map onto a z-level that already has objects on it,
+		you will have to handle the removal of those objects. Otherwise the new map will
+		simply load the new objects on top of the old ones.
+
+		Also note that all type paths specified in the .dmm file must exist in the world's
+		code, and that the /dmm_reader trusts that files to be loaded are in fact valid
+		.dmm files. Errors in the .dmm format will cause runtime errors.

+/*
+	This file will explain what a 'submap' is.  Basically, they are smallish maps which are loaded on top of
+the main map, using the dmm suite's map loading functionality.  Generally this will be done by the game
+automatically to sprinkle the play area with hidden buildings and treasure, baddies, or something along
+those lines.  Admins can also manually place these down where-ever and whenever they want, potentially
+loading it into a new Z-level, for events and such.
+
+	Submaps have two parts, the map .dmm file itself, and a /datum/map_template object which describes the map.
+Both should be included inside the correct places.  Submaps are divided based on where the game expects to place
+them, and the folder containing them also has their map template file.  The divisions are mainly based around
+thematic and location differences (e.g. space, caves, outdoors, asteroid, etc).
+
+	When a submap is loading, the game will 'lock' certain parts of itself, disallowing the loading of a second map until the first
+finishes.  When this is happening, atmospherics is also disabled, to prevent ZAS from displacing things and
+venting unfinished rooms.  There is some noticable lag if the loading takes awhile, but it remains playable
+and it doesn't lock up the came entirely.  Small submaps should load in less than a second, while loading, say, polaris3.dmm
+generally takes the server a minute or two, so try to not make your submap too large if possible.
+
+	You can use /area/template_noop and /turf/template_noop to act as 'void' areas/tiles, which won't be applied to the
+main map.
+
+	Map template datums can have the 'annihilate' var set to TRUE if you need to clear everything where the submap
+is being loaded (to clear trees, etc).  Be sure to not load the map on top of anything valuable to you when using that, like
+irreplacable objects or players, as they will all get deleted if annihilate is on.  If you load the submap before
+other objects have a chance to spawn (before random map gen), you shouldn't need to use annihilate.
