"packf" packs messages into the so-called "ms" format (messages delimited
with lines of four control-A's.)  I believe "mail -f" wants to see them
delimited with "\n\nFrom <user> <ctime>".  A simple shell script could
easily do this, however.  Something like:

	for i in `mhpath +folder messages`
	do
		echo "From noone `date`"
		cat $i
		echo ""; echo ""
	done > outputfile

If you didn't delimit the messages somehow, it's going to be tough.
Usually, "Received:" is the first header in a message so I'd check
for that as a pseudo-delimiter.  If you've used MH on these messages,
there may be annotations preceeding the "Received:" lines, so you'll
have to check for those as well. (i.e. Forwarded:, Replied: , etc.)
Modifiy the script below as needed.

Here's a script which does a rough job of it.  Extract this somewhere
and run:

	awk -f xtr.awk < inputfile > msgbox
	inc -file msgbox

Of course, if you have any forwarded messages present, they'll be extracted
individually, with any trailing text.
