What data do the asset files in the Library folder track?

The Using External Version Control Systems with Unity mentions that we need to add these files to revision control:

EditorBuildSettings.asset

InputManager.asset

ProjectSettings.asset

QualitySettings.asset

TagManager.asset

TimeManager.asset

AudioManager.asset

DynamicsManager.asset

NetworkManager.asset

But what do these files track exactly? Some of them have pretty obvious purposes like QualitySettings and TagManager, but what about things such as DynamicsManager? When should we expect that to change? It would be nice to know what each one is for and under what conditions they change such that we're not surprised when they do change.

DynamicsManager is physics settings, all the rest are pretty self explanatory

They change whenever you change the settings in their relevant panels, though sometimes they're modified more often, possibly serialized slightly differently
