IMPORTANT: read the first four items in Whats New below. This
discusses INCOMPATIBILITIES between this version of TkMail
and previous versions.


Whats New in v1.6:

      - Major rework of setting names. The number of options was
	becoming so large than some sort of organization was
	needed. I decide to change the settings names to an
	emacs-like scheme. This will mean you will have to update
	your ~/.tkmail file to the new scheme. The file newvar.sed
	is included to help with this task. See the README file.

      - new mf_viewer_hook procedure to be defined by user in
	the ~/.tkmail file which will be sourced once the
	main viewer has been built.  This is were all bindings
	and other commands effecting widgets in the main viewer
	should be put

      - tkmail settings for fonts and colors have been removed.
	Instead use the 'option add' command in your ~/.tkmail
	file.  See example.tkmail for how to do this.

      - vastly more complete emacs bindings with arguments and
	kill ring (still no undo). Since many emacs bindings use
	the Meta key, the keybindings in the previous version that
	use the Alt key have been switched over to using the F1
	key as a prefix key. Read the KEY BINDINGS section in the
	help file for more info.

      - at startup, TkMail will recurse through subdirectories
	in your Mail folder directory to create cascading
	menus in the Folder, Copy, and Move menus. The new
	setting mf(menu-depth-max) controls maximum depth of pull
	right menus.

      - new Recent menu item that contains latest accessed
	folders for open, copy, and move

      - elm or bsd aliases files can be read at startup selectable
	 with the mf(mail-alias-file) and mf(mail-alias-type) settings

      - new FCC: entry widget in compose window to specify a 
	different file to record the message in beside that set
	with mf(mail-record)

      - new compose menu item to expand the aliases in the entry
	 widgets so you can see to what exact addresses it will be
	 mailed before sending

      - a button after entry widgets in Compose window that lets you
	edit long address lists in a text widget or use the file
	selector box for FCC:

      - new mouse and key bindings to insert selection with
	the mail prefix at the beginning of each line

      - middle mouse button on Compose and Reply button will 
	insert current message without prefix. Same with the
	Insert Mesg button in the compose window.

      - moved all the online help text into its own file

      - new settings mf(mail-read-ask) and mf(mail-read-max) to
	be prompted before reading in long messages

      - new setting mf(insert-strip) to strip headers from 
	included messages

      - can do searching inside the header listbox

      - added a message log text widget to which all important
	messages and errors are logged to and can be referred
	back to using a Log menu item in the Help menu

      - new mf(menu-sender-list) setting for arbitrary mapping
	of email address to file name for saving

      - a quick button 2 click will insert selection in text
	widgets while button 2 and drag will do scanning

      - aliases now can contain other aliases (recursive)

      - new mf(compose-addr-postfix) settings to hold a default
	machine destination to append to addresses that lack one

      - file selection box now recognizes the ~ character
	and doesn't bomb on directories with special characters

      - new setting mf(compose-quick-forward) to choose between
	using the Compose window for forwards or just typing
	in an address

      - new settings mf(insert-prefix-sig) which contains string to
	insert between message and signature (mainly "--")

      - quick decode will handle multiple enclosures in the same mesg

      - will create directories that don't exist if specified
	in a filename to save or copy to.  You will be prompted
	for confirmation

      - safer incorporation routine that should hopefully work 
	for everyone

      - new %W, %S, %D substitutions for print command that put in
	the sender, subject and date

      - watch cursor will appear in text widgets when TkMail is
	working

      - can rebuild folder menus and reread alias file from
	inside TkMail

      - new setting mf(viewer-beep-empty) to evaluate when the
	system folder is emptied

      - folder menu will signal that it is full with last entry
	of "+++chopped+++"

      - use of alternate editor no longer requires access to the
	Tk send mechanism

      - primitive auto filling mode
