# LocalWP Integration Script for WordPress Plugin Development
# For use by AI coding assistants and developers
#
# This script manages LocalWP sites for testing the plugin.
# Creates standardized test sites with consistent URLs.
#
# URL Patterns:
#   Single site: {plugin-slug}-single.local
#   Multisite:   {plugin-slug}-multisite.local
#
# Usage:
#   ./bin/localwp-setup.sh create [--multisite]
#   ./bin/localwp-setup.sh sync
#   ./bin/localwp-setup.sh reset
#   ./bin/localwp-setup.sh info
#
# Examples:
#   npm run localwp:create              # Create single site
#   npm run localwp:create:multisite    # Create multisite
#   npm run localwp:sync                # Sync plugin files
#   npm run localwp:reset               # Reset to clean state
