📦 Setup Instructions

Follow these steps to set up and run the project on your system:

1. Clone the Repository

git clone <your-repo-link>
cd Version-control-pbl

2. Compile the Project

Navigate to the src directory and run make to build the project:

cd src
make

This will compile the code and generate the vcs executable inside the src/ directory.

3. (Optional) Add vcs to Your PATH

To use vcs from anywhere in the terminal:

export PATH=$PATH:$(pwd)

You can also add this line to your shell config (~/.bashrc, ~/.zshrc, etc.) for persistence.

🚀 Ready to Use!

Now you're ready to use your custom VCS. Try commands like:

vcs init
vcs add <filename>
vcs commit "Initial commit"
vcs log
vcs status
vcs checkout <commit_id>
