Defined in:

Overview

A group of cops, ready to be called on duty to inspect files. Team is responsible for selecting only relevant cops to be sent on duty, as well as insuring that the needed forces are sent along with them.

For performance reasons, Team will first dispatch cops & forces in two groups, first the ones needed for autocorrection (if any), then the rest (unless autocorrections happened).
