That is incorrect (IMO). On a file basis you can turn off most preamble things via the relevant OPTIONS keyword. On a project basis you could set the relevant variable. See org-publish-project-alist. I guess you could make a clever function that sets the org-html-preamble based on some heuristics and add it to one of hooks that are run before parsing. See e.g. org-export-before-parsing-hook. > 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? org-html-preamble-format is a template, it seems, that is used by org-html-preamble, which can also take a string or a function. In practice I always use org-html-preamble in ox-html projects. > Finally, how do I get the current date into the preamble?

Hmm. Does %d or %C work? See org-html-postamble-format. Hope it helps, Rasmus -- I almost cut my hair, it happened just the other day
