+datastorage
+===========
+
+Helper mod to manage players data.
+All the mods can acces a single file (container) and easily have the data saved/loaded for them.
+
+Usage
+-----
+
+	local data = datastorage.get(id, ...)
+
+Returns a reference to a data container.  The id is normally a player name.
+Following arguments are keys to recurse into, normally only one, a string
+describing the type of data, is used.  If the container doesn't exist it will
+be created, otherwise it will contain all previously stored data.  The table
+can store any data.  Player's containers will be saved to disk when the player
+leaves, and all references to the player's data should be dropped.  All of the
+containers will be saved on server shutdown.  To forcibly save a container's
+data use:
+
+	datastorage.save(id)
+
