Ah, I meant to address that too. Since procmail supports Maildir, you
can also convert with procmail. It's probably slower to do so than with
any dedicated conversion utility, but it uses a smaller and consistent
set of tools.

Here's a shell script. It doesn't address permissions or ownerships,
and it doesn't delete the mbox folder.

#!/bin/sh
test -n "$1" || exit 5
convert () {
	MBOX="$1"; export MBOX
	mv "$MBOX" "$MBOX.mbox"
	mkdir "$MBOX"
	formail < "$MBOX" -s procmail "$pmrc"
	# rm -f "$MBOX"
}
pmrc=${TMPDIR-/tmp}/`basename $0`.pmrc
cat <<'PMRC' >"$pmrc"
:0
$MBOX/
PMRC
for folder in "$@"; do
	convert "$folder"
done
rm -f "$pmrc"


N.B. This, too, is untested.
