+define Package/libatomicops/description
+  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.
