I attempted recently to have org-mode use a preamble file when previewing latex-fragments. I used a line like the following:
+LaTeX_HEADER: \input{relative-path-to-file.tex} Unfortunately, the file referenced by the \input{} command doesn't get copied to the location where the preview tex file is compiled. Certainly a way of making it work would be to use an absolute path instead of a relative path, but I really want to have a self-contained portable directory containing both org-mode and preamble files. Would it be possible or sensible to make an option which makes latex-preview-fragment parse +LaTeX_HEADER lines for \input{} commands, and attempt to copy the input files to the preview compilation-folder?
