Servo.h library file for Atmega8?

I bought MicroCamp Mega8 robot kit. Currently I am trying to add a servo motor on this MicroCamp Mega8 Controller Board. But I have a problem that I don't know how to write program to control the servo motor. Can anyone help me?

In fact I need a header file called servo.h for the MicroCamp Mega8 board. It uses 'C' programming language and Atmel Atmega8 microcontroller.
