-      QuickSynergy is a graphical interface (GUI) for easily configuring

-      keyboard between two or more computers.
-
-      Without the need for any external hardware, Synergy2 uses the TCP-IP
-      protocol to share the resources, even between machines with different
-      operating systems, such as Mac OS, Linux and Windows.
-
-      Remember to open port 24800 (used by synergys program) if you want to
-      host mouse and keyboard.";
