			NN-TK

       The TCL/TK code provides  a  GUI  interface  with  command
       menus and buttons.
              The features include:
                     the use of the mouse to select articles
                     a scrolling panel for displaying articles
                     group  selection  using  either of scrolling
                          panel or cascading menus.
              If EXMH is available then there is also:
                     an internal editor for posting items
                     the ability to send and read  MIME  and  PGP
                          messages
                     the  ability  to turn URL's into buttons for
                          passing to MOSAIC (or another WWW reader).

READING
NN-TK follows the NN reading method where all the desired articles of
each group are slected and then read, all the normal NN keys and
commands can be used. The left mouse button can be used for selecting
articles and dragged to select a range of articles. The PAGE buttons
are the equivalent of SPACE key and provides paging through groups,
subject and articles reading any selected articles.

The right mouse button is used for the immediate reading of
selected articles

TCL DIRECTORY 
The tcl directory which contains the NN TK code is in the system NN
lib directory. It can be overriden by having a local version of the
directory in ~/.nn or the current directory. The order of search is
. , ~/.nn , NN lib.

DEFAULTS
Some of the defaults for the nn TK interface are stored in the file
nn-defaults in the tcl directory as X resources, these can be
overridden by creating a file ~/.nn/nn-defaults. Most of these can
still be overridden by options set using the setup menu, which stores
its configuration values in ~/.nn/tk-config as X resources.

EXMH
To include the EXMH routines create a symbolic link named exmh in the
tcl directory pointing to the EXMH lib directory. It isn't necessary
to have MH installed. If EXMH is not available NN will still work, but
will less functionality.

CALLING TCL
The tk extended command can be used for calling tcl/tk from
nn macros
