Re: Writing .el files for org in org?

What if we created a new directory in the repository called "org" which
contains these kinds of files?  It would be analogous to the "lisp"
directory. I don't think we need to have both ob-R.org and ob-R.el in the
repository.

For example I wrote org-ref.org, and I load it like this in my init file
(the intention here is to only tangle the org file when it is newer than
the el file or if there is no el file. for some reason my memory says that
org-babel-load-file was not doing this but that may be a faulty memory).

(if (or
     (not (file-exists-p "org-ref.el"))
     (< (float-time (nth 5 (file-attributes "org-ref.el")))
    (float-time (nth 5 (file-attributes "org-ref.org")))))
    (progn
      (org-babel-tangle-file (expand-file-name "org-ref.org"
starter-kit-dir))
      (load-file (expand-file-name "org-ref.el" starter-kit-dir)))
  (require 'org-ref))

I could see there being something like the lisp path for finding these
files, so that we could just do:

(org-require 'org-ref)

or the org-babel-load-file could be adapted to have a path to search for
files. This way there is no auto-tangling, committing, etc... just regular
version control on the source of the source.
