What about people  who use emacs for other things  than mail ? Or
those  more  generally  who  cannot  send mail  from  emacs  (for

What  about  collecting all  these  infos  and  prepare a  buffer
containing the mail  to be sent (that could  be an alternate mean
to report usages).

Isn't it possible to only  instrument 'eval' to get all functions
(or interesting ones) used ?
