The point is that the nothing in plplot *itself* requires
XML::SAX::Expat, not that XML::SAX::Expat is needed at all. You just
need the db2x_* utilities. Whatever packages provides those need to be
concerned about XML::SAX::Expat, not plplot.

Argh, looks like there is a bug in docbook2X 0.8.7 that causes
--to-stdout to be ignored, so that doesn't work. Looks like this has
been around for a while so make sure you aren't ending up with an empty
plplotdoc.texi in addition to the_plplot_plotting_library.texi.
But, I think I've figured out how to fix this in the xml source. What I
don't like it that it changes the <title> but I haven't found a way
around this yet. Not sure what else it affects. In any case, this
generates a proper .info file now.

These could go anywhere in the "bookinfo" section. Watch the line wrap
above.
