  To convert your MH folders to BABYL folders, first run the following
  script on your Mail directory.

    #!/bin/sh

    for f in Mail/*; do
	if [ -d $f ]; then
	    touch msgbox
	    folder=`basename $f`
	    echo -n packing $folder ...
	    packf +$folder
	    echo done
	    mv msgbox Mail-rmail/$folder
	fi
    done

  This assumes you don't have nested folders. Your rmail folders will
  be left in $HOME/Mail-rmail in MMDF format which rmail can read.
  Then run rmail-input for each folder, which converts each folder
  into BABYL format.

  Be sure not to append any messages before they are converted from
  MMDF to BABYL, since there may be really strange results.
