     *
     * ```yml
     * close: true
     * comment: Check the specs on the rotary girder.
     * ```
     *

     *
     * ```js
     * // Load config from .github/config.yml in the repository
     * const config = await context.config('config.yml')
     *
     * if (config.close) {
     *   context.octokit.issues.comment(context.issue({body: config.comment}))
     *   context.octokit.issues.edit(context.issue({state: 'closed'}))
     * }
     * ```
     *
     * You can also use a `defaultConfig` object:
     *
     * ```js
     * // Load config from .github/config.yml in the repository and combine with default config
     * const config = await context.config('config.yml', {comment: 'Make sure to check all the specs.'})
     *
     * if (config.close) {
     *   context.octokit.issues.comment(context.issue({body: config.comment}));
     *   context.octokit.issues.edit(context.issue({state: 'closed'}))
     * }
     * ```
     *
     * Config files can also specify a base that they extend. `deepMergeOptions` can be used
     * to configure how the target config, extended base, and default configs are merged.
     *
     * For security reasons, configuration is only loaded from the repository's default branch,
     * changes made in pull requests from different branches or forks are ignored.
     *
     * If you need more lower-level control over reading and merging configuration files,
     * you can `context.octokit.config.get(options)`, see https://github.com/probot/octokit-plugin-config.
