So my next task is to learn about the HTML preamble. >From reading the docs, it looks like all of my org files have to share a single HTML preamble, which is set in my .emacs file through either the org-html-preamble variable, the org-html-preamble-format variable, or the org-publish-project-alist variable. There is no way to tell a specific Org file "This is your HTML preamble." Is that correct?
Why are there two different variables org-html-preamble-format and org-html-preamble if the org-html-preamble variable can perform all of the tasks of org-html-preamble-format and more? Finally, how do I get the current date into the preamble? I see that I can specifically set a date, and I see the current date in a comment at the top of my exported HTML, but I can't figure out how to get the current date out of the comment and into my preamble. Thanks. --hymie!
