devio does not seem to be maintained anymore. I intend to salvage it
with the plan to orphan it in three weeks. Please notify me if you object.

I am hereby orphaning devio. Please only consider adopting if you have
the time and skills to maintain it.

Description: correctly read (or write) a region of a block device
  devio is a command line program to read correctly from mtd character
  (and other block) devices. devio allows access to specific regions of
  the device and allows output of data from specific locations.
  The primary difference between devio and other command line
  utilities, such as dd and cat, is that it is not stream based - it
  writes directly into the object rather than reading and writing a
  stream of data.
