Are you looking to use this for or payload modification ?

Allows users to structure complex configuration files in a hierarchy (using YAML, JSON, etc.) and dynamically inject these variables into text-based templates (e.g., configuration files, script templates). How it Works:

Eliminates duplicated data across multiple server configs.

Easily switch configurations between development, staging, and production.

Set up a root configuration file that inherits, overrides, or merges settings from child files (e.g., global.yaml -> environment.yaml -> host.yaml ).

Use placeholder syntax within target files to define where data should be injected.
