(defn some-step [args ctx]
  (chaining args ctx
            (shell/bash injected-ctx "/ " "echo hello ")
            (shell/bash injected-ctx "/ " "echo world ")))

  (always-chaining args ctx
                   (run-tests injected-args injected-ctx)
                   (if (= :failure (:status injected-args))

Functions that allow you to use LambdaCDs pipeline mechanisms inside a step, i.e. chain several steps together:

```clojure
(defn some-step [args ctx]
  (chaining args ctx
            (shell/bash injected-ctx "/ " "echo hello ")
            (shell/bash injected-ctx "/ " "echo world ")))

(defn some-step-with-error-handling [args ctx]
  (always-chaining args ctx
                   (run-tests injected-args injected-ctx)
                   (if (= :failure (:status injected-args))
                     (publish-test-failures injected-args injected-ctx))))
```

Functions that help in adding the ability for a step to be killed.

Functions that support build steps in dealing with metadata

Functions and macros that simplify dealing with a steps user readable output (`:out`). Two approaches are provided:
The _printer_ approach that gives full control over what will be provided as output and the `capture-output`-approach that just redirects all stdout.
