Code Owner diff tool

This tool helps to identify which files in a repository are changing ownership when a GitHub CODEOWNERS file changes.

Usage

$ codeowners-diff --help
usage: codeowners-diff [-h] [-r REPO_ROOT] [base_ref] [head_ref]

get a summary of the changes to code owners between two refs

positional arguments:
  base_ref              default: main
  head_ref              default: HEAD

options:
  -h, --help            show this help message and exit
  -r REPO_ROOT, --repo-root REPO_ROOT
                        git repository to run the tool in (default: current directory)

By default, the tool will show the changes in ownership between the current revision and main.

The output is GitHub-flavoured Markdown.
