That's it for Tutorial 6.  With very little effort we've managed to extend the previous single-threaded server to an implementation which allows runtime selection of single or multi-threaded operation.  In Tutorial 7 we'll extend that again to allow a thread-pool choice in addition to the current two.

For reference, here's the file list again:

• Makefile
• client_acceptor.h
• client_handler.cpp
• client_handler.h
• server.cpp
• fix.Makefile
