aws/serverless-application-model ? reverse-engineered prompt

Build me a Python project that works like the AWS SAM transform, so a simple serverless template can be turned into a normal CloudFormation template.

I want to be able to write a template with AWS SAM resources like a Lambda function, and have the tool expand it into the underlying CloudFormation resources, including the IAM role and sensible defaults. Please include clear examples and enough tests so I can trust the output. It should be easy to run locally, and the code should follow the project docs and existing AWS SAM behavior as closely as possible.

If you need to check the latest AWS docs or examples online to match how SAM is supposed to behave, go ahead. I’d also like the repo to include helpful development and usage instructions so someone can understand how to work on it and verify changes without guessing.
