// QUAKED FuncRotDoorSpawn (0 .5 .8) ? START_OPEN REVERSE
// DOOR_DONT_LINK TOGGLE X_AXIS Y_AXIS
// if two doors touch, they are assumed to be connected and operate as a unit.

// TOGGLE causes the door to wait in both the start and end states for a trigger event.

// START_OPEN causes the door to move to its destination when spawned,
// and operate in reverse.  It is used to temporarily or permanently
// close off an area when triggered (not usefull for touch or
// takedamage doors).

// You need to have an origin brush as part of this entity.  The
// center of that brush will be
// the point around which it is rotated. It will rotate around the Z
// axis by default.  You can
// check either the X_AXIS or Y_AXIS box to change that.

// "distance" is how many degrees the door will be rotated.
// "speed" determines how fast the door moves; default value is 100.

// REVERSE will cause the door to rotate in the opposite direction.

// "angle"	determines the opening direction
// "targetname"	if set, no touch field will be spawned and a remote button or trigger field activates the door.
// "health"	if set, door must be shot open
// "speed"	movement speed (100 default)
// "wait"	wait before returning (3 default, -1 = never return)
// "dmg"	damage to inflict when blocked (2 default)
// "sounds"
// 0)	no sound
// 1)	stone
// 2)	base
// 3)	stone chain
