Changing the Git history of your repository using a script[1]

We've created a script that will change any commits that previously had the old email address in its author or committer fields to use the correct name and email address.

Before running this script, you'll need:

• The old email address that appears in the author/committer fields that you want to change
• The correct name and email address that you would like such commits to be attributed to

1. Open a terminal.
2. Create a fresh, mirror clone of your repository:

greyltc

#!/usr/bin/env python3
"""script that puts holes into pcb"""
import pcbnew


class HoleMaker(object):
    """puts holes into a pcb, units are mm"""

    board_filename = None
    pcb = None
