minor modes survey

From: thi
Subject: minor modes survey
Date: Wed, 7 Feb 2001 11:35:44 -0800

i'd like to figure out what minor modes people use w/ other minor modes
in order to (help the GNU emacs developers) determine a useful policy
for keybindings.  if people could mail me privately w/ usage info, that
would be great.  please use the code below to help automate processing.
(eval the two functions, do `M-x compose-mode-usage-mail', add any
additional comments, and type `C-c C-c' to send.)

the expiration for this survey is 21-FEB-2001.  responses after that
date will be silently ignored.  i will publish aggregate info (only) to
this list.

thanks in advance for your participation!
