Language newbie

[alan-s]

I want to understand how multi language with mambel fish works but am short on time to install and test.
So........

Is it the case that you have just one install and different language files which the visitor then gets a drop down select and chooses a preferred language?

I can see how menu items and titles might generically be replaced by MambelFish but can't quite see how categories and content would work in multpile languages.

I have a potential client who wants a site in four different languages. They are all multilingual and going to keep 4 copies of each site going but I was wondering how I might fulfill such a request with Mambo and mambofish assitance.

Any explanations and tips welcome.
