Route Planner Cross-Platform Launcher
=====================================

This script provides cross-platform compatibility and path detection.
Use this for:
- Cross-platform execution: python route_planner.py
- Systems where main.py might have issues
- Advanced users who need platform detection

Most users should use the installed 'route-planner' command instead.
