Where can I find the pins_arduino.h of ATmega328?

Development Tools IDE 1.x

I'm using the promini board and have found there are several pins_arduino.h under the path: 'arduino-1.6.8\hardware\arduino\avr\variants'. But all of them are not related to ATmega328 or promini,so I wanna ask is there some document that define the pins of promini??

It's at arduino-1.6.8\hardware\arduino\avr\variants\eightanaloginputs\pins_arduino.h but that just changes the value of NUM_ANALOG_INPUTS to 8. The actual pin definitions are in arduino-1.6.8\hardware\arduino\avr\variants\standard\pins_arduino.h

Thanks a lot, I just thought the stadard one is for Atmega8 & 168 because its command.
