Question about pear 1.7.0RC1

Hello! I noticed that in PEAR 1.7.0RC1 there is a new file role 'www' This is great. I think it's the same as the Role_Web from pearified but now it's in pear. I'm still new to pear installer. I set the www_dir using pear config-set Now my question is: how do I get this value from my scripts? I mean what's the way to get the value that was set with pear config_set? Thank you again. -- Open Source ALL content management with streaming video http://wiki.sharedlog.com
