Example from dm_bounce.

env_godrays_controller is a point entity available in Black Mesa since Crossfire Update (22 december 2015 year) and removed in 24 november 2017 year update. This entity controls Crepuscular Rays, the first version of godrays effect before the november update. The november update brought local point and sun new lights (also with new spot light which don't support godrays), this made env_godrays_controller with crepuscular rays useless, this is why it was removed. However, it is still not removed from the FGD file, you also still can choose the crossfire update in beta branches list.

Todo: Fix some stuff. May better describe functions. Investigate and document some keyvalues and functions. Clean up english. Add more issues if you'll find.
