-To support the specification of a subdirectory for dependencies that are sourced from Git repositories, we need to extend the kcl.mod file structure. This involves adding an optional `subdirectory` field under each dependency.

 ## 7. Conclusion
-By extending the kcl.mod file to include a subdirectory field for Git-based dependencies, users can now specify and manage dependencies that reside in specific subdirectories of a Git repository. This enhancement will enable kpm to download only the necessary parts of large repositories, significantly improving performance when dealing with monorepos. The user interface remains intuitive, and the implementation leverages Git's sparse-checkout feature to achieve the desired functionality.
