defmodule Mix.Tasks.Needle.New.Ctx do
  @moduledoc """
  Creates a new context project within an umbrella project.

  It expects the command to be run inside an umbrella application's
  `apps` directory:

      $ cd my_umbrella/apps
      $ mix needle.new.ctx PATH [--app APP] [--module MODULE]

  This task is intended to create a bare context project without web
  integration, which serves as a core application of your domain.

  ## Options

  It supports the same options as the `needle.new` task.

  See `mix help needle.new` for details.

  ## Examples

      $ mix needle.new.ctx hello_ctx
