"""
Example Flask server for serving remote validation configurations.

This demonstrates how to set up a simple HTTP server to provide
validation configurations for biotope projects.

Usage:
    python remote-validation-server.py

Then in your biotope project:
    biotope config set-remote-validation --url http://localhost:5000/validation.yaml
