%description
This package provides semi-portable access to hardware-provided
atomic memory update operations on a number architectures.  These might
allow you to write code:

* That does more interesting things in signal handlers.

* Makes more effective use of multiprocessors by allowing you to write
  clever lock-free code.  Note that such code is very difficult to get
  right, and will unavoidably be less portable than lock-based code.  It
  is also not always faster than lock-based code.  But it may occasionally
  be a large performance win.

* To experiment with new and much better thread programming paradigms, etc.
