<?php
// This file contains support functions for preference display and editing
// Preferences are represented in two ways:
// - As a PHP structure (usually called $prefs)
// - As XML (usually called $prefs_xml)
// Various functions are defined below for converting between these forms,
// and also to/from HTML form elements
// functions to parse preferences XML into a struct
//
// This XML has the general structure
// <preferences>
// <dont_run_if_user_active/>
// <low_water_days>1.3</low_water_days>
// ...
// <project>
// <url>...</url>
// <resource_share>45</resource_share>
// ...
// <project-specific>
// ... (arbitrary project-specific XML)
// </project-specific>
// </project>
// ... (other projects)
// </preferences>
