In this project I implemented a version-control system that mimics some of the basic features of the popular system Git. Mine was smaller and simpler.

A version-control system is essentially a backup system for related collections of files. The main functionality that Gitlet supports is:

1. Saving the contents of entire directories of files. In Gitlet, this is called committing, and the saved contents themselves are called commits.
2. Restoring a version of one or more files or entire commits. In Gitlet, this is called checking out those files or that commit.
3. Viewing the history of your backups. In Gitlet, you view this history in something called the log.
4. Maintaining related sequences of commits, called branches.
5. Merging changes made in one branch into another.

Pintos is a simple operating system framework for the 80x86 architecture. It supports kernel threads, loading and running user programs, and a file system, but it implements all of these in a very simple way. In the Pintos project, I strengthened its support in all three of these areas. I also added a virtual memory implementation.
