hello. I have been experimenting with the i18n module to creat a multi lingual site, and so far I have been able to translate nodes as expected. however, I need help with how to get the 'language dependent variables' to work. I know I should be modifying the config file, but where is that file? anybody who ever done this please help me out.

I want in the end to have different site title, mission statement, footer, menu, etc. for each language.
