============

Purpose:
--------
  IOBUF is an I/O buffering library that can reduce the I/O wait time 
  for programs that read or write large files sequentially. IOBUF 
  intercepts I/O system calls such as read and open and adds a layer of 
  buffering, thus improving program performance by enabling asynchronous 
  prefetching and caching of file data.
