 # Gitoxide-Based Submodule Manager
 
 Provides core logic for managing git submodules using the [`gitoxide`](https://github.com/Byron/gitoxide) library, with fallbacks to `git2` and the Git CLI when needed. Supports advanced features like sparse checkout and TOML-based configuration.

 ## Usage
 
 Use this module as the backend for CLI commands to manage submodules in a repository. See the project [README](README.md) for usage examples and configuration details.
