I want to place a box around the verbatim environment. Unfortunately,
when I do the following,

	% Make boxes. Inspired from Exercise 21.3 from TeXbook.
	\def\boxit#1{\vbox{\hrule\hbox{\vrule \kern1.2pt
	 \vbox{\kern1.2pt{ \parindent 0pt
	 \tt #1}\kern1.2pt}\kern1.2pt\vrule}
	 \hrule}}
	
	\boxit{
	\begin{verbatim}
	this better come out in boxed verbatim mode ...
	\end{verbatim}
	}

I get the following error message:

	
	! Argument of \@xverbatim has an extra }.
	<inserted text>
	                \par
	<to be read again>
	                   }
	\boxit ...vbox {\kern 1.2pt{ \parindent 0pt \tt #1
	                                                  }\kern 1.2pt}\kern 1.2pt\v...
	
	\boxed ...t}{\boxit {\vbox {\hsize \textwidth #1}}
	                                                  } \end {flushleft}
	l.523 }
	
	? h
	I've run across a `}' that doesn't seem to match anything.
	For example, `\def\a#1{...}' and `\a}' would produce
	this error. If you simply proceed now, the `\par' that
	I've just inserted will cause me to report a runaway
	argument that might be the root of the problem. But if
	your `}' was spurious, just type `2' and it will go away.
	
Well, I have tried many other ways. I actually tried using the
definition of verbatim in boxit, but that didn't work either. Do you
know a way to do this? Doesn't matter if it is simple or complicated.

BTW, I want the box to be the same size as textwidth, i.e., from the
global leftmargin to the global rightmargin, and not the current
left margin. For example,

	if my left margin is here ..

Thanks in advance.
