Accounting Tutorial scripts

Hi hi, I'm working through the tutorial on Accounting - to make sure I've set it properly etc; but I'm struggling to find the shell scripts that are mentioned for generating the test accounting packets. I searched the filesystem for "bob-acct-start.sh" and looked in github, but wasn't able to find them. Would someone be so kind as to point me in the right direction please? Thank you in advance for your time and consideration!
