+* This class implements a Text_Wiki_Parse to find source text marked as a
+* definition list.  In short, if a line starts with ':' then it is a
+* definition list item; another ':' on the same line indicates the end
+* of the definition term and the beginning of the definition narrative.
+* The list items must be on sequential lines (no blank lines between
+* them) -- a blank line indicates the beginning of a new list.
