+This package provides semi-portable access to hardware provided
+atomic memory operations.  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.
+
+For details and licensing restrictions see the files in the doc
+subdirectory.
