[OS X TeX] Framed Shaded Box

[David Arnold]

Hi,

Consider:

\documentclass{article}
\usepackage{geometry}
\usepackage{xcolor}
\usepackage{framed}

\definecolor{shadecolor}{gray}{0.8}

\begin{document}

{\noindent \itshape Starting in the Fall of 2009, all students enrolled in Math 376 (Prealgebra) at College of the Redwoods will receive a free copy of this textbook on a CD on the first day of class. A printed version of this textbook may be purchased from the college bookstore (707-476-4130).}

\begin{shaded}

\end{shaded}

\end{document}

I am trying to figure a way to put a frame around the shaded text, but no success thus far. I'm trying to duplicate the framed shaded region on:

http://msenux.redwoods.edu/PreAlgText/

Any suggestions?

Thanks.
