-% The\stydsc{line-style=solid} \kvdesc{solid}
-% line style is the default. In fact, if you make no calls to \cs{SetMCRule}
-% after loading \mcrule, the column divider will behave exactly as it does with
-% the ordinary \pkg{multicol} package. You can alter its width and color either
-% with the
-% \kvdesc{width} and \kvdesc{color} keys described in
-% sections \ref{sec:width} and \ref{sec:color}, respectively, or you can set the
-% width directly by changing the value of \cs{columnseprule} and renewing the
-% \cs{columnseprulecolor} macro. Like all line styles, the solid line can be
-% repeated as many times as you like (see section \ref{sec:repeats}).
+% The\stydsc{line-style=solid} \kvdesc{default} and \kvdesc{solid} line styles
+% are nearly the same, except that the \kvdesc{solid} line (as of version 1.1)

+%
+% You\stydsc{line-style=dashed, extend-top=-16pt, extend-bot=-16pt} can specify
+% an additional amount by which the top or bottom of the rule projects beyond
+% the column's natural length with the keys \kvdesc{extend-top} and
+% \kvdesc{extend-bot}, each of which can be set to a dimension expression.
+% Extending the top of the rule with a positive dimension will push the columns
+% down from any preceding material. A positive value for \kvdesc{extend-bot}
+% does the same in the other direction when a column ends in the middle of a
+% page, but the rule will extend into the the bottom margin if the column goes
+% to the end of the page, and so you probably only want to use this in very
+% limited situations where you need a special effect for one small
+% \env{multicol} environment. Negative values for both keys may be more 
+% generally useful, as they have the effect of shrinking the rule. This
+% behavior is illustrated with the rule for this section.
+%
+% The \kvdesc{extend-fill} key is a boolean option that, when set to true, will
+% extend the rule to occupy any space between the bottom of the columns and the
+% end of the text area. Providing the key with no value is equivalent to
+% |extend-fill=true|. This option has no effect unless the \pkg{multicol}
+% package is loaded.
+%
+% If you want text below the \env{multicols} environment when using
+% \kvdesc{extend-fill}, you can reserve space for it with
+% \kvdesc{extend-reserve}, which takes a dimension expression specifying the
+% vertical space to leave available after the rule. If the value is greater
+% than zero, the height of the extended line will be reduced by the reserved
+% amount plus the value of \cs{multicolsep}. In other words, you only have to
+% specify the actual space you need for the text itself, not the space that 
+% \pkg{multicol} adds automatically below the columns. Note that if the amount
+% you request for reserved space is less than the amount actually available at
+% the end of the page, the rule will not extend below the columns and you
+% probably will find this material spilling onto the next page anyway.
