changing the title of listings

This question cropped up in the channel yesterday and is quite obvious in the source 

but not so in the documentation. If you want to change the name of the listing (think

localization) then you need to change three things.

\renewcommand\lstlistingname{Quellcode}
\renewcommand\lstlistlistingname{Codefragmente} 

\def\lstlistingautorefname{Alg.}

The first line is the name at every listing, the second the title for the list of 

listings and the third if you want to autoref a listing.
