What's a GNU Regex?

openNMS uses the classes from the java.util.regex package.  The syntax  
includes much that is borrowed from Perl, and is documented here:

http://java.sun.com/j2se/1.5.0/docs/api/java/util/regex/Pattern.html

That document mentions negative lookahead, so I think that will work  
here.  If it does, please let me know -- although I consider my own  
regex-fu reasonably strong, I'd never heard of negative lookahead.
