how to apply an older patch in local GIT repository?

Can a git repository inherit or extend files from another repository?

• In a scenario where a team is working on a project in a repository, and then a completely different project that uses styles and some code from the original project repository is created, how can the repositories be set up such that the changes made to those global files in the original repository are also made accessible in the new repository?

• Answer:

  I think what you are looking for is called git submodules. It links to a specific commit in another git repo instead of tracking all the changes of the other project (in the case where you just include the code in your project). I would say be careful with submodules though because it's easy to get carried away.
