    docbook2latex.xslt:
        translates a DocBook XML source into a LaTeX source file,
        which can be processed with pdflatex to produce a
        pretty PDF file.

        Note: In the LaTeX output, this XSLT encodes all quotes
        with \QUOTE{} commands, which are not defined in this
        file. This is because XSLT does not support regular
        expressions natively and therefore it is rather difficult
        to implement proper "pretty quotes" (different glyphs for
        opening and closing quotes) in XSLT. The doc/manual/
        makefile solves this by running sed over the LaTeX source
        once more, replacing all \QUOTE{} commands with
        \OQ{} and \CQ{} commands, which _are_ defined to the
        pretty quotes for English in the LaTeX output generated
        by this XSLT (see below).

    Command Synopsis elements.

    We treat each command element inside a cmdsynopsis as the start of
    a new paragraph.  The DocBook HTML converter does so too, but the
    manpage one doesn't.

    sbr and linebreaks made by latex should be indented from the base
    command level. This is done by the \hangindent3em\hangafter1 bits.

    We exploit the default paragraph indentation to get each command
    indented from the left margin.  This, unfortunately, doesn't work
    if we're the first paragraph in a (sub*)section.  \noindent cannot
    counter this due to when latex enforces first paragraph stuff. Since
    it's tedious to figure out when we're in the first paragraph and when
    not, we just do \noindent\hspace{1em} everywhere.

       xsltprocNewlineOutputHack - emits a single new line.

       Hack Alert! This template helps xsltproc split up the output text elements
                   and avoid reallocating them into the MB range. Calls to this
                   template is made occationally while generating larger output
                   file.  It's not necessary for small stuff like header.

                   The trick we're playing on xsltproc has to do with CDATA
                   and/or the escape setting of the xsl:text element.  It forces
                   xsltproc to allocate a new output element, thus preventing
                   things from growing out of proportions and slowing us down.

                   This was successfully employed to reduce a 18+ seconds run to
                   around one second (possibly less due to kmk overhead).
