There's an example in the manual.  Here's another example:

In org:

    #+begin: thanks :pretext "We have received valuable comments from"
    #+end:

The function:

    (defun org-dblock-write:thanks (params)
      "Reads THANKS file in same folder and format.
    PARAMS can hold :filename, :keyword, and :prefix"
      (when (file-exists-p (or (plist-get params :filename) "THANKS"))
        (insert (or (plist-get params :keyword) "#+thanks: ")
                (plist-get params :prefix) " "
                (replace-regexp-in-string
                 ".*?\\(,\\)[^,]*\\'" ", and"
                 (mapconcat
                  'identity
                  (remove-if
                   (lambda (str) (string-match-p "^\\s-*$" str))
                   (split-string
                    (with-temp-buffer (save-excursion
                                        (insert-file-contents "THANKS"))
                                      (flush-lines  "^\\s-*$" (point-min) (point-max))
                                      (buffer-string)) "\\s-*\n+\\s-*"))
                  ", ")
                 nil nil 1)
                ".")))


You might want to add (org-dblock-update t) to some export hook.
