Can't find ShiftPinNo.h library

Hello, I'm playing for the first time with shift registers on Arduino and I encountered some troubles about this example from playground.

To make it work is necessary to include this ShiftPinNo.h library, but I can't find it anywhere! :'( In the sample I downloaded from that page, there's ShiftOutX.h but no ShiftPinNo.h. :neutral_face:

Could someone help me please?

Thank you sir for your attention. :wink:
