ClipSpy registers itself as a clipboard viewer. Nothing magical there. But when the contents of the clipboard change, ClipSpy enumerates all the data formats on the clipboard (there may be many) and displays them all in the left-hand pane. Clicking on a format in the list shows the data that was placed on the clipboard in the right-hand pane. The right pane shows the raw data as well as the ASCII representation, similar to the memory debug window in MSVC.

The left-hand pane also registers as a drop target, so you can drag any data from a program that supports drag-and-drop, drop it over the list, and ClipSpy will show all the data that the drag source provided. Again, the formats are listed in the left-hand pane, and clicking a format shows the corresponding data in the right-hand pane.

@Mods: please move.
