FGD Code
Todo: add InputFilter keyvalue
@SolidClass base(Targetname, Parentname, Global, Inputfilter, EnableDisable) = trigger_brush
[
DontMessageParent(integer) : "Don't alert parent" : 0 : "When 0 forwards OnStartTouch, OnEndTouch outputs or Use input to parented entity"

output OnUse(void) : "Fired when the Use input is given. "
output OnStartTouch(void) : "Fired when an entity starts touching this trigger. The touching entity must pass this trigger's InputFilter to cause this output to fire."
