/*
* This class provides an automatic synchronization of the X11 Clipboard and Selection
* buffers. There are two configuration options in the kdeglobals configuration file,
* in the [General] section:
* - SynchronizeClipboardAndSelection - whenever the Selection changes, Clipboard is
* set to the same value. This can be also enabled in Klipper.
* - ClipboardSetSelection - whenever the Clipboard changes, Selection is set
* to the same value. This setting is only for die-hard fans of the old broken
* KDE1/2 behavior, which can potentionally lead to unexpected problems,
* and this setting therefore can be enabled only in the configuration file.
*
* Whenever reporting any bug only remotely related to clipboard, first make
* sure you can reproduce it when both these two options are turned off,
* especially the second one.
