Note: If you open the .nib file, you will find that
1) There is a panel with the scrollView that appears in the TARInspector content inspector panel. The content view of this panel is loaded as described in GeneralRef/WMInspector.rtf.
2) There are only 2 connections: One from the files owner (a TARInspector object, which is a subclass of WMInspector... see GeneralRef/WMInspector.rtf) to the window (This is used by the WMInspector to load the content view of the panel into the inspector window. ) and one from the files owner to the text object in the ScrollView (allows the inspector to update the display).
3) The instructions are easily edited in RTF form. You can see why I decided to not put them in the code files!
4) The scroll view is centered in the panel and no larger for a reason: if it is moved or made larger, things won't look right in the inspector when the scrollview is loaded. If you move it up or down even a single pixel, it will be clipped! (I made it as large as possible.)
