===============================================================================
                PREAMBLE

    GoPATH is the new name of what we previously called Go. Like Go,
    GoPATH components include a set of libraries (for graphical
    application developpement) still called "Go" libraries, a set of
    editors (for graphical presentation design) called "Go companions"
    and the documentation.

    In order to promote GoPATH, a part of it is distributed on the network
    with a restrictive copyright (see below the Copyright notice).
    Any commercial use of GoPATH is controlled by a license.


    In the release note (below), restrictions concerning the public
    release are listed.

                               GoPATH

                   A Path To Object Oriented Graphics


                               ABSTRACT

    GoPATH is an environment for graphical and interactive application
    development. At this time, it includes a object oriented toolkit: Go
    and utilities: Go Companions.

    Go is a portable and extensible 2D graphic object library for
    application data presentation and interaction. Go intends to extend
    with powerful graphical capabilities the standard  toolkits
    (ie. OSF/Motif(TM) or MS-Windows(TM)). Go allows to create,
    to modify and to compose graphical objects. These objects can
    be displayed in a window (or a pixmap) or can be written in a
    PostScript(TM) format. When displayed on the screen, the user can
    directly manipulate objects, the user events are interpreted with
    respect to UI description files. An external stream format allows
    to export/import structured graphical objects, it can be used to
    store/retrieve structured graphics on disk or to exchange graphics
    between applications (cut/copy/paste). Available predefined
    graphical objects are geometric, formatted texts, images,
    graphs, trees and grid.

    The Go Companions are utilities which come with the Go library in
    order to help application developers to draw the graphical
    presentation and to define its behavior.  Mainly, Go Companions
    include graphical objects editors (godraw, gopaint, gowrite,
    gohyper) and resource editors (gopen, godash, gobrush, gocolor, ...).
    The Go Companions constitute for the application  programmer
    a real 2D presentation builder.

    Go as well as editors runs on a number of Unix(TM) environments
    (Bull, Sun, SGI, MIPS, IBM,  SCO,  ...) and on MS-Windows(TM) 3.1.

    Major features coming with the 1.2.0 release are:

       Go librairies
       =============

        o New GoUI:
            Go User Interactions have been rewritten! Here we have
            broken the compatibility with Go-1.1.

            The term GoUI now represents both the "Go User Interaction
            Toolkit" and the GoUI class.

            The Go User Interaction Toolkit includes the following
            basic classes:
              - GoSensor: This object class allows to define sensitive
            areas (areas interested by user events).
            GoSensor subclasses which are Gos can graphically
            show the sensitive areas (see GoHyper). When
            receiving an event (from a GoUI instance), GoSensor
            starts an interaction (if not already started) and
            sends the event to it.

              - GoUI: There is one GoUI instance per GoInterf (window).
            It is responsible for dispatching events to sensors.
            It also manages sensor asking for the keyboard focus
            or grabs, and generates "Enter/LeaveSensor" events.

              - GInteractor: This object class is the execution
            context of an interaction. A GInteractor executes
            an interaction program (GInteractorPgm). The
            GInteractor class is an abstract class. For example
            GGrabber and GTranslator classes are subclasses
            of GInteractor.

              - GInteractorPgm: This object class is the abstract
            class for the interaction program class. A
            GInteractorPgm subclass can be a C++ program or
            a piece of interpretable code like the simple
            GoUI language for event translation or Wool for
            more sophisticated interactions (not yet available).

        o GoStreams:
            A portable binary format (GoBinary) is now available.
            It allows to reduce the disk or memory space (up to 75%)
            and the coding/encoding time. It is used by default
            for the "cut/copy/paste" operations.

        o GoInterf:
            Double click for XGoInterf, scalable fonts with X.V11R5.

        o GoTextual extensions:
            non-textual segments, it is now possible to include
            images, geometric objects, ... in a text object. These
            non-textual segments follow the textual behavior.

            extra-baseline: this functionality provides capabilities
            for indiced or exponentiated segments (useful in
            mathematical formulae, trade mark notations, ...)

            style management: this allows to define style objects
            which are used to highlight text segments on the textual
            objects. Style attributes include: font, color, underline
            position/color/thickness, extra-baseline, ...

            margins (top, bottom, left, right)

            merging and extracting functions

        o New Text Formatters:
            Formatter objects are available in order to fill Text
            objects in:
                a list of boxes
            several columns
            a circle
            These formatters inherits capabilities (justification,
            international hyphenation, presentation, ...).


        o Application Oriented Objects (Extensions library):
            A new library, called "Go Extensions", comes with
            GoPATH 1.2.0. It contains application
            oriented objects for minimizing the Go based
            application development effort.

            These objects includes:

            Clipboard Interface (cut/copy/paste support),
            Converters (export/import support),
            Filters (TIFF, GIF),
            GoEditors (base for writing Go Editors)
            ResEditor (base for writing Resource Editors)
            Help (help support)


        o Xb Widgets (Unix version):
            Some Motif(tm) widgets have been developed to be used
            in some Go Companions, they are gathered in the libXb.a
            library.


       Go Companions
       =============

        o godraw:
            Clipboard management
            Binary streams management
            New object interactions

        o gohyper:
            Sensor editor. Allows to create sensitive areas on
            top of graphical object and edit a script as the
            behavior.

        o gowrite:
            Text editor. Allows sophisticated text formatting
            using Formatter objects.

        o gopen:
            Pen editor. Allows to create named or unamed Pens and
            to manage Pen dictionaries. Copy/Paste can be used
            in conjunction with applications.

        o gocolor:
            Color editor. Allows to create named or unamed colors
            and to manage Color dictionaries. Copy/Paste can be used
            in conjunction with applications.

            On X/Unix, the rgb.txt format is managed.

        o godash:
            Dash editor. Allows to create named or unamed dashes
            and to manage Dash dictionaries. Copy/Paste can be used
            in conjunction with applications.


       Scripts
       ======

        o CreateGoClass is a script allowing to create the skeleton
          (.cc and .h files) of a Go subclass including the Metaclass.


                -+-+-+-+-

    Uncompatibilities with Go-1.1:

        The only uncompatibility between Go-1.1 and GoPATH 1.2
        is GoUI. A document (src/doc/Papers/old-new-GoUI) gives the
        way to move from the old GoUI to the new one.


        The GoSensor format in the GoStream has been modified. If
        some GoSensors exist in your ASCII GoStream remove them
        (by using your prefered editor).

                -+-+-+-+-

    Further extensions:

        o GoInterf class:
            The cursor management is not complete.

        o XGoInterf class does not support
            DTriple click
            Images with bit_per_pixel which is not 1 or 8.

        o Resource Editors: gobrush, gotextbrush,

        o Go Editors: gopaint

        o Go Desktop: some utilities integrated in a desktop
                (clipboard, converter, print, ...).

        o Filters:
            Simple popular formats like XPM or PCX, and
            JPEG compression.

        o Graphic widget:
            XmNeditable resource is not implemented.

        o PostScript interface is incomplete (some level2 capabilities
            need to be simulated).


    Bugs:

    The following bugs will fixed with patches.

            o On-Line Help is not yet available in GoWrite, GoPen,
          GoDash, GoColor.

        o Revision of the Go Advanced Programmer's Manual.

        o Some ergonomic unconsistencies in Go Editors,

        o Link errors when linking examples on Sun4/60 with C++ 2.1
          using shared libraries.
          It is possible to link by calling the    XtToolkitInitialize()
          function at the beginning of the main().

        o

                -+-+-+-+-

    GoPATH 1.2.0 Public Release:

    The GoPATH 1.2.0 Public Release functionalities are similar to
    the functionalities available in Go-1.1, so people who started
    to work with Go-1.1 will be able to continue their work (except
    for some text capabilities).


    The public release restrictions:

        Go Kernel:
        GoBinary: portable binary coding for GoStream. It allows
        to reduce the disk/memory space and increase the time coding/
        encoding.

        Predefined Go's:
        Some GoText extensions:
          - sophisticated formatters: multicolumn, multibox, circle.
            The single column formatter is still delivered.
          - non-textual segments: the capability to include non-textual
            segments (images, geometric objects, ...) in a GoText
            is not delivered.
          - indiced or exponentiated segments, this capability is
            useful for mathematical formulae for example.
          - style management for text segment highlighting

        The GoScrolledText (no more delivered):
            This text object allows to scroll characters (horizontally)
            or lines and pages (vertically). This object is useful
            in tabular or spread sheet cells.
