Subject Re: [Latka]Following references
Date Thu, 01 Jan 2004 09:48:36 GMT

I provided this patch a couple of weeks ago and got no reaction. So I 
just want to ask whether there is anybody who has an eye on patches and 
further development of this component.

BTW: Has there ever been a release of Latka?
