+%description -n libatomic_ops-devel 
+Provides implementations for atomic memory update operations on a
+number of architectures. This allows direct use of these in reasonably
+portable code. Unlike earlier similar packages, this one explicitly
+considers memory barrier semantics, and allows the construction of code
+that involves minimum overhead across a variety of architectures.
