How to change default language of anaconda installer?

[Zdenek Pizl <pizl@xxxxxxxxxxxx>]

Hallo all,

 I am trying to change default language (english) to another one. I'd like to 
make anaconda installer speaking Czech from the beginning not from the fourth 
or fifth screen.

 Is it possible to do it by changing code of anaconda or can I set up some 
enviromental variables to do it?

	Thanks,
