+ * This file implements every system specific function for Mac OS X.

+ *  It includes the init function:
+ * 
+     void rfbScreenInit(void)
+ * 
+ * the function to get the address of the framebuffer:
+ * 
+     char *rfbGetFramebuffer(void)
+ *
+ *  keyboard functions:
+ * 
+     void KbdAddEvent(down, keySym, cl)
+        Bool down;
+        KeySym keySym;
+        rfbClientPtr cl;
+     void KbdReleaseAllKeys()
+ * 
+ *  the mouse functions:
+ * 
+     void PtrAddEvent(buttonMask, x, y, cl)
+        int buttonMask;
+        int x;
+        int y;
+        rfbClientPtr cl;
+ * 
+ *  and the EventLoop:
+ * 
+     void runEventLoop()
+ * 
+ * These six functions have to be defined by every VNC server using
+ * libvncserver.
+ *
+ * The main function just calls runVNCServer. This is different
+ * for more complex users of libvncserver.
