[texhax] multipage framed boxes, open across page boundary

[Niall Mansfield]

I'm looking for multipage framed boxes.

I get almost what I need with
	\begin{framed}
	...
	\end{framed}

except that if a frame crosses a page boundary, it should appear as
below, to make it clear that the second-page box is a continuation of
the first, i.e. first box is open at bottom, second is open at top.

|                                            |
|       stuff on first page                  |

	<no line at end>

	...  <newpage> ...

	<no line at top>


|       stuff on second page                 |
|                                            |

There was a posting back in August ("[texhax] multipage framed boxes")
      http://www.tug.org/pipermail/texhax/2005-August/004481.html
but I'm afraid I didn't understand how to do what someone suggested,
viz.: "use the framed environment and ensure that the frame will
extend down beyond the normal area for the text block. Then, set a
flag when one starts a framed environment ...".

Is there a package that provides this functionality?
