Subject: What the hell is the => operator?

    I've seen this in some ruby code but I have no idea what is going on. 
I'd do a google search on it but... I don't search for '=>' and I don't know 
how to describe it in english so that the context will be this!
    I've seen this operator used in, what seems to me, to be totally bizarre 
contexts.  As far as I know, it's only used in hash definitions.  However, 
it's used in both Rails and scRUBYt.  It looks something like this:


method_call :symbol => false do
    # do something here
end

another_method  random_var, :symbol => :other_symbol do
    # do something else
end


    Can someone explain to me what is going on here?
    Thank you...
