Drill file for CAM processing. Should it be 2:4 leading?

I am using the CAM generation script from Sparkfun. In there it indicates that an excellon drill file is created with 2:4 leading. Is this the same drill file that i can use with your PCB service too?

Do you have your own CAM processing script for Eagle CAD?

Thanks!
