[Boost-users] Merging sorted iterators?

Hi, I have a bunch of iterators over some sorted input from several big files which do not fit into memory. What I would like to have is one iterator which allows me to iterate over the combined sorted input (of course, the result should be sorted, too). Something like this: -------\ --------\ ... ---- --------/ -------/ Is there a class in boost which allows me to do this in a simple way? Thanks and regards, Roland
