logic_auto
From Valve Developer Community
logic_auto is a point entity available in all Source games. It fires outputs immediately after a map loads, unlike most other entities that wait for input first. It can be set to check a global state before firing, which allows you to fire events based on what took place in a previous map.
If the "Remove on fire" flag is set the logic_auto is deleted after firing. 
To do: This may cause problems with delayed outputs.
Warning:Attempting to directly access or modify the player may cause Access Violation errors, because the outputs are fired before the player has spawned. Adding a slight time delay may overcome this.Keyvalues
