Message-Id: <E1IFU5R-0006Tw-Bv@lionel-hutz.w3.org>

Update of /sources/public/2002/css-validator/org/w3c/css/index
In directory hutz:/tmp/cvs-serv24877/org/w3c/css/index

Added Files:
	IndexGenerator.java 
Log Message:
This file is used to generate the index pages
This can be called from a script (indexgenerator.sh or .bat)
But, when the first request is made on the server, it'll also launch this (see init() in org.w3c.css.servlet.CssValidator)
The index are generated only if they don't exist or if the template (org/w3c/css/css/validator.vm) has been changed

--- NEW FILE: IndexGenerator.java ---
/**
 * This class is used to generates the index pages
 * of the CSS validator in all the availables languages
 * it'll create the outputs validator.en.html, validator.fr.html, ...
 * according to the template file validator.vm
