cat << EOF
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.
