Today I`m learning "Socket Programming HOWTO" and improve my English

I have read Socket programming Python Docs... There are two objects in Python 2.7 I insert to this post helpl(socket) and Soxypy readme.txt
There are 7 links here ...and huge help(socket) file... and SocksiPy link and readme.txt ... And the question "Who use the SocketServer object" is still a charade for me...
