I have patched up htmlfontify[1] to support fontification of odt source
blocks. I am planning to submit the patch to emacs-devel.

Till such time as this patch is integrated in to official Emacs, I would
like to check-in a copy of htmlfontify.el into the contrib dir. Will
there any objection to this?

I am attaching sample before and after files to tickle the curiosity.
