More specifically, I have
file1.org and
file2.org, and each of them have three footnotes ([fn:1], [fn:2], and [fn:3]). I want to create
file3.org, which simply merges
file1.org and
file2.org, with the contents of
file2.org coming after the contents of
file1.org. The problem is that the footnote calls ([fn:#]) in the file2 section will end up pointing the file1 footnotes. What I really want is to automatically renumber all the footnotes [fn:1]...[fn:6], but I don't know how to do this, given that org permits multiple footnote calls to the same footnote.
