"""
This script is part of the pytest release process which is triggered manually in the Actions
tab of the repository.

The user will need to enter the base branch to start the release from (for example
``6.1.x`` or ``main``) and if it should be a major release.

The appropriate version will be obtained based on the given branch automatically.

After that, it will create a release using the `release` tox environment, and push a new PR.

Note: the script uses the `gh` command-line tool, so `GH_TOKEN` must be set in the environment.

[deploy](https://github.com/pytest-dev/pytest/actions/workflows/deploy.yml) workflow, using these parameters:

* `Use workflow from`: `release-{version}`.
* `Release version`: `{version}`.

Or execute on the command line:

```console

After the workflow has been approved by a core maintainer, the package will be uploaded to PyPI automatically.
