The previous implementation read the entire file into memory and then processed it. This version uses reasonably-sized buffers and can handle files of any size. Since this new conversion code is a bit more complicated, a test suite has been added which can be run on ordinary Unix systems. GitOrigin-RevId: acc7be277103fad1da2d0ca16d1a84be11802fbf
