 Hi Heime,

eev has a function, called "find-eppm", that takes a sexp, expands it
with macro-expand, pretty-prints the expansion, and displays the
pretty-printed code in a temporary buffer. If you'd like to try it,
install eev, run this,

  (require 'eev-load)

and then type `C-x C-e' after the last parenthesis here:

  (find-eppm '

  (define-minor-mode MAIN-mode
    "Help 1"
    :init-value t
    :global t
    :lighter (propertize " MAIN" 'face 'region))

  )

The reason for the "(require 'eev-load)" is explained here:
