# @file GitHub Runner Registration
# @brief Registers a GitHub action runner with GitHub
# @description
#     This script registers the host as a self-hosted GitHub runner with scope set
#     in the `.user.github.runnerOrg` input in the `.chezmoi.yaml.tmpl` file. If your organization is `megabyte-labs`, then
#     the value of `.user.github.runnerOrg` should be `megabyte-labs`. A self-hosted runner is an application
#     that that allows you to run tasks from GitHub CI.
#
#     This script adds 3 labels to the runner: self-hosted, _hostname_, and _operating-system family_.
#
#     The script automatically acquires the GitHub Action runner token (as long as you specify your `.user.github.runnerOrg` value in `.chezmoi.yaml.tmpl`).
#     In order to authenticate with GitHub, you should have the `GITHUB_TOKEN` environment variable in place with the appropriate permissions
#     specified when you generate the token.
