Subject: AtmOps Library

AtmOps is a simple library that provides a uniform interface 
for performing atomic operations across all hardware and 
software configurations of the Mac OS. It provides atomic 
compare-and-swap, addition, and bit set/clear/test functions.

The library is designed for application-level code (i.e., it's 
not suitable for writing device drivers).  Full source is 
included.
