run-tests.php options

Hi all I've been trying to figure out what all the configuration settings (command line and ENV) do in run-tests.php. I have documented them here:http://wiki.php.net/wiki.php.net/qa/runtests/configuration; some settings can be specified by bit command line and ENV variables. There are two points to this: 1) I'd like regular users to tell me what they would really like to see re-implemented in the new version, I have a view on some already but I'm don't want to make a 'yes/no' decision without some feed back. Please would you reply with your 'must have' options? 2) I thought it might be useful for new users to document the ENV settings, and say where they are the same as command line options. Zoe
