+    - the function principle of the windows clipboard:
+      a data provider offers all formats he can deliver on the clipboard
+      a clipboard client ask for the available formats on the clipboard
+      and decides if there is a format he can use
+      if there is one, he requests the data in this format
+
+    - This class inherits from IDataObject and so can be placed on the
+      OleClipboard. The class wraps a transferable object which is the
+      original DataSource
+    - DataFlavors offered by this transferable will be translated into
+      appropriate clipboard formats
+    - if the transferable contains text data always text and unicodetext
+      will be offered or vice versa
+    - text data will be automatically converted between text and unicode text
+    - although the transferable may support text in different charsets
