Hi Abdul. Thanks for asking.
The support package readme file contains the following information:
"INSTALLING THE ADAFRUIT MOTOR SHIELD LIBRARY (to be done only once):
As better explained in the next step, this you will also need to upload eiter the motor_v1.pde or the motor_v2.pde sketch on the board.
NOTE that if you don't have the adafruit motor shield and you don't plan to use it, you might also SKIP THIS STEP.
Also note that the "official" Arduino (not Adafruit) motor shield: (<http://arduino.cc/it/Main/ArduinoMotorShieldR3>) does not require any additional library, works fine with the chipkit32 boards, and can be used with this package right away. Therefore if you plan to use the official motor shield then you can safely skip this step."
I hope that helps.
