/**

7
* This class implements a Text_Wiki_Parse to find source text marked as a
8
* definition list.  In short, if a line starts with ':' then it is a
9
* definition list item; another ':' on the same lines indicates the end
10
* of the definition term and the beginning of the definition narrative.
11
* The list items must be on sequential lines (no blank lines between
12
* them) -- a blank line indicates the beginning of a new list.
