Sharing documents that are highly configured, but don't rely on the
user's Emacs configuration, is one goal of "reproducible research"
carried out with Org mode.

In general, it is possible to move the configuration into the shared Org
mode document and then use Local Variables to load the configuration
when the document is opened, or when the user refreshes the setup.

The first step is to put the configuration into one or more Babel source
code blocks in the shared document and give each source code block a
name.  Then set up Local Variables to called the named source code
block(s) using the org-sbe (formerly, sbe) function.

Here is a fragment of the Local Variables section I'm using on a
self-contained Org mode document.

# Local Variables: 
# eval: (require 'ox-latex)
# org-hide-macro-markers: t
# org-entities-user: nil
# eval: (and (fboundp 'org-sbe) (not (fboundp 'sbe)) (fset 'sbe 'org-sbe))
# eval: (sbe "user-entities")
# End:

Where the source code block named "user-entities" is:

*** User Entities
The following source code block sets up user entities that are used frequently
in my work. I use the various =*macron= commands to typeset Hawaiian
language words with what is known in Hawaiian as a /kahak\omacron{}/.

#+name: user-entities
#+begin_src emacs-lisp
  (add-to-list 'org-entities-user '("amacron" "\\={a}" nil "&#0257" "a" "a" "ā"))
  (add-to-list 'org-entities-user '("emacron" "\\={e}" nil "&#0275" "e" "e" "ē"))
  (add-to-list 'org-entities-user '("imacron" "\\={\\i}" nil "&#0299" "i" "i" "ī"))
  (add-to-list 'org-entities-user '("omacron" "\\={o}" nil "&#0333" "o" "o" "ō"))
  (add-to-list 'org-entities-user '("umacron" "\\={u}" nil "&#0363" "u" "u" "ū"))
  (add-to-list 'org-entities-user '("Amacron" "\\={A}" nil "&#0256" "A" "A" "Ā"))
  (add-to-list 'org-entities-user '("Emacron" "\\={E}" nil "&#0274" "E" "E" "Ē"))
  (add-to-list 'org-entities-user '("Imacron" "\\={I}" nil "&#0298" "I" "I" "Ī"))
  (add-to-list 'org-entities-user '("Omacron" "\\={O}" nil "&#0332" "O" "O" "Ō"))
  (add-to-list 'org-entities-user '("Umacron" "\\={U}" nil "&#0362" "U" "U" "Ū"))
#+end_src

Let me know if you have questions.
