"""
VPSC8 Path Fixer - Convert Windows-style paths to cross-platform paths in input files.

This script fixes path separators in VPSC8 input files to ensure cross-platform compatibility.
Run this script if you encounter path-related issues on Linux/macOS systems.

Usage:
    python fix_paths.py [directory]

If no directory is specified, it will process all example directories.
