Rough example of de-databasing MODX elements (as far as humanly possible)

de-database.php

<?php
/**
 * Rough outline script of extracting MODX elements from the database to
 * allow them to be version controlled.
 * 
 * If this script is modified and also run for Snippets, Templates and Plugins
 * then you can start to VCS their source
 * 
 * All that would remain would be triggering a cache-refresh after each deployment
