Example: Moderately complex code generation

[vkleen]

For instance, write a tool, configurable in Nickel, to generate boilerplate code for Bazel build settings for language specific compiler flags.

There is a lot of repetition involved when adding Bazel build settings for specific languages. We could imagine a tool to keep those up to date which is configured from a single place in Nickel. That way we could have a Nickel library to generate instructions for this hypothetical tool and put more specific concerns into Nickel.
