def self.print_help

    Usage: belt destroy <generator> <name> [field:type ...]
           belt d <generator> <name> [field:type ...]

    Removes files and references created by `belt generate`.

    Generators:
      scaffold      Remove model, controller, routes, schema, and views
      resource      Alias for scaffold
      model         Remove an ActiveItem model
      controller    Remove a controller
      auth          Remove Cognito user pool infrastructure
      environment   Remove a deployment environment and tear down infrastructure
      frontend      Remove a frontend directory (use --frontend NAME when several exist)
      views         Remove React pages for a resource

    Environment options:
      --force, -f          Skip all prompts (CI mode)
      --skip-terraform     Delete local files without running terraform destroy

    Examples:
      belt d scaffold post title:string body:text status:string
      belt d model user
      belt d controller comments
      belt d environment staging
      belt d environment dev --skip-terraform
      belt d environment dev --force
      belt d frontend
      belt d frontend --frontend ops
      belt d views post
      belt d views post --frontend ops

    ⚠ This is destructive. Files will be permanently deleted.

    For environments: if terraform state is detected, you'll be prompted to run
    `terraform destroy` first to tear down cloud resources before removing files.
