# Introduction to pathmaster

Pathmaster is a command-line tool for managing your system's PATH environment variable. It provides safe, efficient PATH manipulation with automatic backups and comprehensive validation.

## What is PATH?

The PATH environment variable is a fundamental part of Unix-like operating systems that tells your system where to look for executable programs. When you type a command like `python` or `git`, your system searches through the directories listed in PATH to find these programs.

## Why Use pathmaster?

Managing PATH manually can be risky and error-prone. Pathmaster helps by:

- Safely adding and removing directories
