parser = argparse.ArgumentParser(description=
"""Update copyright headers on files of a range of commits.

This can be used to easily update copyright headers at once on an entire
patchset before submitting.

Only files touched by the selected commits are updated.

Only existing copyrights for the selected holder are updated, new
notices are never automatically added if not already present.

The size of the changes is not taken into account, every touched file gets
updated. If you want to undo that for a certain file because the change to
it is trivial, you need to manually rebase and undo the copyright change
for that file.

Example usage with an organization alias such as `arm`:

```
python3 -m pip install --user --requirement \
  gem5/util/update_copyright/requirements.txt
./update-copyright.py -o arm HEAD~3
```

The above would act on the 3 last commits (HEAD~2, HEAD~ and HEAD),
leaving HEAD~3 unchanged, and doing updates such as:

```
- * Copyright (c) 2010, 2012-2013, 2015,2017-2019 ARM Limited
+ * Copyright (c) 2010, 2012-2013, 2015,2017-2020 ARM Limited
```

If the organization is not in the alias list, you can also explicitly give
the organization string as in:

```
./update-copyright.py HEAD~3 'ARM Limited'
```

which is equivalent to the previous invocation.
