Yeah, I thought about that, but this would not be very practical, as I=20
am still fidling around with the style sheet a lot. With this solution,=20
I would need to commit any minor change.

I still think that having org-html-head and org-html-head-extra behave=20
like org-html-preamble and org-html-postamble would be a great addition,=20
which would offer a lot of flexibility (beyond the use-case listed here).
