<?php

//	Simple single-file doc validation utility, using our php-based `jsdoc` parser. 
//	To be used as a post-commit hook?
// 
//	to use:
//		php -q parsefile.php dojox/data/AndOrReadStore.js
//
//	exits normally (status 0) if OK, with status 255 if failed, other values are from PHP untrapped.
//
//	add --debug to last argument to see output data, eg:
//
//		php -q parsefile.php dijit/_Widget.js --debug
//
//	scan all files prior to running generate/makeCix (considerably faster to detect fatal parser-breaking errors)
//
//		php -q parsefile.php --all
