2.14    ! frystyk    17: The Tee stream just writes everything you put into it into two other
2.2       frystyk    18: streams. One use (the only use?!) is for taking a cached copey on disk
                     19: while loading the main copy, without having to wait for the disk copy
                     20: to be finished and reread it. <P>
                     21: 
2.11      frystyk    22: You can create a T stream using this method. Each stream returns a
                     23: return value and in order to resolve conflicts in the return code you
                     24: can specify a resolver callback function. Each time any of the data
                     25: methods are called the resolver function is then called with the
                     26: return codes from the two streams. The return code of the T stream
                     27: itself will be the result of the resolver function. If you pass NULL
                     28: as the resolver routine then a default resolver is used.<P>
