<dd><p>When we want to use the LaTeX backend with postscript, we write PSFrag tags
to a temporary postscript file, each one marking a position for LaTeX to
render some text. convert_psfrags generates a LaTeX document containing the
commands to convert those tags to text. LaTeX/dvips produces the postscript
file that includes the actual text.</p>
