"""
Simple Launcher Template for Standalone Python GUI Scripts

This template provides a launcher that runs an external Python script
when clicked. No dialog is shown - just click and run.

Usage:
1. Copy this file and rename it (e.g., mygui.py)
2. Update SCRIPT_PATH to point to your Python script
3. Update the class name (e.g., MyGuiDialog)
4. Add to __init__.py: from .mygui import MyGuiDialog
5. Add 'MyGuiDialog' to __all__ list
