doubt regarding working of base_local_planner

Hi all,

I have a small doubt regarding working of base_local_planner. As the base_local_planner requires an odometry information (nav_msgs/Odometry) to get the current speed of the robot, I would like to know how does the base_local_planner uses the odometry message to effectively generate the command velocities (/cmd_vel), I mean what kind of controller does it use or how does it work out? I am more interested in knowing how the odometry message is interpreted to better estimate the command velocities. Can anyone throw some light on it or point me in the right direction.
