Hi there !

I don't quite understand the following method (taken from RESTful
authentication) and can't google the problem since the Goog won't accept
the search term in question ("||=").

The method:

def current_user
    @current_user ||= (login_from_session || login_from_basic_auth ||
login_from_cookie || :false)
end

My question:

I know "||" means a boolean "or", but what does "||=" mean?
Can you translate the above method into a sentence?

Thank you very much for your help!
Tom
