12.4 Include Files
During export, you can include the content of another file. For
example, to include your '.emacs' file, you could use:
#+INCLUDE: "~/.emacs" src emacs-lisp
The first parameter is the file name to include. The optional second
parameter specifies the block type: 'example', 'export' or 'src'. The
optional third parameter specifies the source code language to use for
formatting the contents. This is relevant to both 'export' and 'src'
block types.
You can visit the included file with C-c '.
