+The remainder of this chapter will describe customizing the Text
+widget.  The Text widget may be customized by subclassing, or by
+creating new sources and sinks.  Subclassing is described in
+detail in Chapter 7; this section will describe only those things that
+are specific to the Text widget.  Attributes of the Text widget base
+class and creating new sources and sinks will be discussed.

+<!-- .LP -->
+The Text widget is made up of a number of different pieces, with the
+Text widget as the base widget class.  It and the AsciiText widget are
+the only true "widgets" in the Text widget family.  The other pieces
+(sources and sinks) are X Toolkit objects and have no window
+associated with them.  No source or sink is useful unless assigned to
+a Text widget.

+Each of the following pieces of the Text widget has a specific purpose,
+and will be, or has been, discussed in detail in this chapter:

+This is the glue that binds everything else together.  This widget reads
+the text data from the source, and displays the information in the sink.
+All translations and actions are handled in the Text widget itself.

+This object is responsible for displaying and clearing the drawing area.
+It also reports the configuration of the window that contains the
+drawing area.  The TextSink does not have its own window; instead it does
+its drawing on the Text widget's window.

+This widget is a subclass of the Text widget.  When created, the AsciiText
+automatically creates and attaches either an AsciiSrc and AsciiSink, or a
+MultiSrc and MultiSink, to itself.  The AsciiText provides the simplest
+interface to the Athena Text widgets.
