No worries, that will come quick :-)

I'm not familiar with the code of letgut.cls, but in case 'ltx-code' and
friends take keyval's form the listings package, you can do something
like this:

   (LaTeX-add-environments
    '("bookreview" LaTeX-env-args
      (TeX-arg-key-val (("title")
                        ("reviewer")
                        ("bibkey")
                        ("frontcover")
                        ("price"))))
    '("ltx-code" LaTeX-env-args
      [TeX-arg-key-val (LaTeX-listings-key-val-options)])
    '("ltx-code-result" LaTeX-env-args
      [TeX-arg-key-val (LaTeX-listings-key-val-options)])
    '("ltx-code-external-result" LaTeX-env-args
      [TeX-arg-key-val (LaTeX-listings-key-val-options)]
      TeX-arg-file))

I put that in the letgut.el I have and it works.  The file is attached.

Best, Arash
