There is an extended (but unofficial) version of the (X)Emacs package
"mh-e" available at the nmh web/ftp site. This package was developed
by Darryl Okahata.
There is a link to this package (along with its README) on the
primary nmh web page at:
http://www.math.gatech.edu/nmh/
Or you get grab it directly at:
ftp://ftp.math.gatech.edu/pub/nmh/mh-e/mh-e.tar.gz
You can read its README file at:
ftp://ftp.math.gatech.edu/pub/nmh/mh-e/README
If you have any questions about this package, you'll need
to ask Darryl.
