Re: Vertical justification

    When a cartouche becomes larger than a page 

I think this would be very difficult to implement.  Personally I think
@cartouche should never have been invented, but anyway, it's meant for
small examples that you want to set off from the text.  One cartouche
going on for pages and pages just isn't going to work.  Sorry.

    When I use pdftexinfo the text is vertically justified over 
    the page. 

This is the intended behavior, at least if I'm understanding what you're
describing.  In general, it's desirable to have text vertically
justified over the page, so that the top and bottom lines match up from
one page to the next.

If your document has lots of large unbreakable boxes, like cartouches,
then that will be very difficult to page break, by its nature.  You
might like to use the plain TeX \raggedbottom command in this case to
tell TeX not to worry about the bottom margin.  In Texinfo, this would
be:
@tex
\gdefs=1 \raggedbottom
@end tex

I think this may mess up the top margin too, but it's what's there now.

Hope this helps,
