Hi, Attached is a modified version of Benchmark.pm and a patch for the change. This is a documentation change only: I added a section describing the Benchmark object, as I just spent some time looking at the code to work it out. I'm sending this manually, because while following the instructions in perlhack, perlbug barfed. I'm not subscribed to p5p, so include me on any replies please, at least if you want me to do something :-) Neil
