Zip is a small (.25 meg), high-speed, general-purpose, cut-and-paste
editor written for Silicon Graphics IRIS-4D workstations by Tom Davis.
Its user interface is similar to that of jot and Showcase.  It also 
understands many of the same speed-key combinations as EMACS.  It 
works quite well on large files, on C or C++ source code, and it 
allows you to edit arbitrary binary files as well.  It has been heavily 
used internally and seems to be quite solid.

Features include:

    Infinite Undo/Redo
    Macros
    Command multipliers
    UNIX filters on selected text
    Incremental search
    Electric-C mode

How to install zip:

zip.tar.Z is a compressed tar file containing:

    zip.changes		-- ASCII description of new features
    zip			-- IRIX 4.0.x executable
    zip.3.3		-- IRIX 3.3.X executable
    zip.int		-- experimental internationalized zip
    zipxgizmo		-- IRIX 4.0.x gizmo for X11 selection
    Install		-- an installation script
    zip.doc		-- on-line documentation
    zip.tutorial	-- on-line tutorial
    zip.tex		-- TeX version of manual (65 pages)
    zip.ps		-- PostScript version of zip.tex
    quickref.ps		-- 2 page PostScript quick-reference card
    zip.ftr		-- WorkSpace file
    zipExecutable.fti	-- WorkSpace file
    zipExecuting.fti	-- WorkSpace file
    zip.wsrc		-- WorkSpace file

There is a file called "Install" that will copy files to the right
places, and rebuild the WorkSpace rules.  It must be run as root.
If you can't run as root, you can still install zip (except for the
WorkSpace rules) as follows:

The files "zip" and "zipxgizmo" go somewhere in your path 
(the Install file will put them in /usr/sbin).

The files "zip.doc" and "zip.tutorial" go by default in /usr/local/doc.
If the environment variable ZIPDIR is set, they should be put there.

--------

If you are still running NeWS (IRIX 3.3), you can get a pretty good
zip executable from:

    zip.3.3

Put it in your path, and call it "zip".  In this case, you don't need
the file "zipxgizmo", and the X-style cut, copy, and paste commands
won't work.  zip.3.3 cannot read the X-format font files, so you're
stuck with the default font.

An experimental internationalized version of zip for roman alphabets
on a 4.0.X system is also available.  It is called:

    zip.int

It understands X-keyboard remappings.  The internationalization is
undocumented except here and in the zip.changes file.
