To Install:

Provided you have Tcl/Tk installed, you don't have to do anything!  Place the 
downloaded hierarchy wherever you like.  Then just double-click on 'alphatk.tcl' 
to run AlphaTk. To open a document with AlphaTk do: 'wish runalpha.tcl document'.

You should have Tcl 8.1 or newer installed.  It may work with Tcl 8.0.4 or newer, but
there are many known problems, and AlphaTk is not supported on releases older than 8.1.
You can get the latest Tcl distribution from <http://www.scriptics.com/>.

If you downloaded an 'AlphaTk-standalone' archive, then you don't need to have
Tcl/Tk installed, just double click on the AlphaTk executable to run it.  However
due to current limitations of the utility used to make the executable, it lacks
some features of the Tcl/Tk dependent version (e.g. dde support on windows).

Optional extras:

AlphaTk can be localised!  Currently there is only a British english locale provided which 
modifies a few spellings from the American default.  However, by setting the locale in
the 'International' preferences dialog, and by creating locale files (in the Localisation
directory), you will be able to modify all of AlphaTk's menus, dialogs etc.

AlphaTk comes with documentation (in its Help menu).
