I hacked up the latex spitter to allow me to change the latex, I recommend
reading the 'extending lore' part of the howtos if this doesn't provide you
enough context. What this following code (that I use) does is puts a box
around the verbatim text:

in my spitters.py:

class LivewiresLatexSpitter(latex.ChapterLatexSpitter):
    def visitNode_pre(self, node):
        self.writer('\n\n\\begin{fmpage}\n\\begin{verbatim}\n')
        buf = StringIO()
        latex.getLatexText(node, buf.write)
        s = buf.getvalue()
        self.writer(latex.text.removeLeadingTrailingBlanks(s))
        self.writer('\\end{verbatim}\n\\end{fmpage}\n\n\n')

in my book.tex:

\newlength{\fmwidth}
\setlength{\fmwidth}{\textwidth}
\addtolength{\fmwidth}{-.5in}

\newsavebox{\fmbox}
\newenvironment{fmpage}[0]
    { \begin{lrbox}{\fmbox}\begin{minipage}{\fmwidth}}
    {\end{minipage}\end{lrbox}\vspace{1em}\fbox{\usebox{\fmbox}}\vspace{1em}}

I'll be happy to tarball up my documentation tree and send it to you off-list
if you want a working example.

Stephen.
