New Revision: 842
WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba-web&rev=842
Log:
Using a simpler JS sniff. I don't need all the variables
provided by the Netscape "Ultimate Sniff".
Worked up my own smaller variable list as part of my JS
toolkit work; thought I'd use it on samba.org, too.
