+// GENERIC STEAM SPREAD SYSTEM
+
+//Usage: set_up(number of bits of steam, use North/South/East/West only, spawn location)
+// The attach(atom/atom) proc is optional, and can be called to attach the effect
+// to something, like a smoking beaker, so then you can just call start() and the steam
+// will always spawn at the items location, even if it's moved.
+
+/* Example:
+var/datum/effect_system/steam_spread/steam = new /datum/effect_system/steam_spread() -- creates new system
+steam.set_up(5, 0, mob.loc) -- sets up variables
+OPTIONAL: steam.attach(mob)
+steam.start() -- spawns the effect
