This library provides a set of classes that provide an operating
system abstraction from a majority of OS provided functions. All of
the sipX projects use this library to ensure easy porting to any
operating system. The library currently provides classes that
encapsulate functions and operations for:

* Threads
* Locks and Mutexes
* Semaphores
* Messages and Queues
* Timers
* Time and Date
* Sockets
* File and Directory
* Operating System Processes
* Dynamic loading of shared libraries and symbols
