%D This style looks a lot like number 22. This time we don't
%D cycle but build up the page. One can click on the text go
%D to the page wanted. Clicking on the titl ebrings you to the
%D previous page.

%D We use a simple two||color scheme.

\definecolor[DotColor][r=.5,g=.6,b=.7]
\definecolor[TopColor][r=.7,g=.6,b=.5]
\definecolor[BotColor][TopColor]

%D We will not delay page building.

\let\BuildPage\relax

%D Instead, we will flush a page for each summary. The main
%D layer is build up anyway, but we need to overlay the
%D current summary.

%D The title page is not added to the main layer (or
%D actually, it is, but we erase the layer before it's
%D used).
