+/*QUAKED trigger_music (1 0 0) ?
+Background music trigger (when this is used, the cdtrack line in mapinfo must not be used, and there MUST be a default target_music).
+When triggered, its effect is turned off until triggered again.
+-------- KEYS --------
+targetname: The name other entities can use to target this entity
+noise: the music to play (as full sound file name)
+volume: the volume (default: 1)
+fade_time: fade-in time
+fade_rate: fade-out time
+-------- SPAWNFLAGS --------
+START_OFF: the trigger is off initially
+*/

+/*QUAKED trigger_gravity (.5 .5 1) ? STICKY START_OFF
+An area where gravity differs from the rest of the map.
+This acts as a modifier over the normal gravity (sv_gravity). eg: 0.5 is half the normal gravity, 2 is twice the normal gravity.
+-------- KEYS --------
+gravity: gravity offset in this area, defaults to 0 if not set
+noise: sound to play when an entity enters the gravity zone, leave empty to disable
+targetname: you can use this to target the grazity zone with a trigger, which will toggle it when activated
+-------- SPAWNFLAGS --------
+STICKY: entities keep their gravity after leaving the gravity zone
+START_OFF: when targeted, the gravity zone starts off and is enabled upon triggering
