 IBM's compiler is not implementing all the features of C++11 standard, especially it's lacking the concurrency features that the standard brings. This will at some point be fixed and was therfore looking at a way reduce the effort to switch from a specific implementation to the C++11 standard one. This projetc is the resulting code.
 
 
-This wrapper intends to bring these feature by implementing C++11 interface and using the  pthread library.  Of course, as it is a replacement of C++11 features, it is best to use the standard implementation if your compiler support it. This can be done rather easely by using the standard namespace `std` instead of this library's specific one `pthread`.:w
