Module: Kettle::Dev::CIHelpers

Defined in:
lib/kettle/dev/ci_helpers.rb

Overview

CI-related helper functions used by Rake tasks and release tooling.

This module only exposes module-functions (no instance state) and is
intentionally small so it can be required by both Rake tasks and the
kettle-release executable.
