&quot;type the character ^&quot;.
<P>
+ This version of Alpine contains an enhanced algorithm for justification,
+ which allows you to justify text that contains more complicated quote
+ strings. This algorithm is based on pragmatics, rather than on a theory,
+ and seems to work well with most messages. Below you will find technical
+ information on how this algorithm works.
+
+ <P>
+ When justifying, Alpine goes through each line of the text and tries to
+ determine for each line what the quote string of that line is. The quote
+ string you provided is always recognized. Among other characters
+ recognized is &quot;&gt;&quot;.
+
+ <P>
+ Some other constructions of quote strings are recognized only if they
+ appear enough in the text. For example &quot;Peter :&quot; is only
+ recognized if it appears in two consecutive lines.
+
+ <P>
+ Additionaly, Alpine recognizes indent-strings and justifies text in a
+ paragraph to the right of indent-string, padding with spaces if necessary.
+ An indent string is one which you use to delimit elements of a list. For
+ example, if you were to write a list of groceries, one may write:
+
+ <UL>
+ <LI> Fruit
+ <LI> Bread
+ <LI> Eggs
+ </UL>
+
+ <P>
+ In this case the character &quot;*&quot; is the indent-string. Aline
+ recognizes numbers (0, 1, 2.5, etc) also as indent-strings, and certain
+ combinations of spaces, periods, and parenthesis. In any case, numbers are
+ recognized <B>ONLY</B> if the line preceeding the given line is empty or
+ ends in one of the characters &quot;.&quot; or &quot;:&quot;.
+ In addition to the explanation of what constitutes a paragraph above, a
+ new paragraph is recognized when an indent-string is found in it (and
+ validated according to the above stated rules).
+
