Note that this is (and always was) a terrible hack and we really should replace it with something reasonable which wouldn't need changing every time linuxdoc-tools evolve. I also needed to include a patched version of LinuxDocTools.pm, because the original one explicitly refused to work with a non-linuxdoc DTD. The authors of linuxdoc recommend to use sgmltools-lite in such cases, but it would mean rewritting our formatting rules to the DSSSL language which I don't dare to speak about here :)
