+A Ruby DSL and helper utilities for building CloudFormation templates dynamically.
 
 Written by [Bazaarvoice](http://www.bazaarvoice.com): see [the contributors page](https://github.com/bazaarvoice/cloudformation-ruby-dsl/graphs/contributors) and [the initial contributions](https://github.com/bazaarvoice/cloudformation-ruby-dsl/blob/master/initial_contributions.md) for more details.
 
 ## Motivation
 
-Cloudformation templates often contain repeated stanzas, information which must be loaded from external sources, and other functionality that would be easier handled as code, instead of configuration.

-Consider when a userdata script needs to be added to a Cloudformation template. Traditionally, you would re-write the script by hand in a valid JSON format. Using the DSL, you can specify the file containing the script and generate the correct information at runtime.

-Additionally, Cloudformation templates are just massive JSON documents, making general readability and reusability an issue. The DSL allows not only a cleaner format (and comments!), but will also allow the same DSL template to be reused as needed.

 - `tag(tag)`: add tags to the stack, which are inherited by all resources in that stack; can only be used at launch
