How do install EPC header on the ASR router? or is it now part of the IOS?

There was a discussion of using the router to look at the trace capture from the router, I downloaded the EPC header, but don't know to install.  Is there any documentation on how to install the script file onto the ASR router?  Thank you

Which script is this exactly?
