How to install and start using zk:

Use the NT command shell, because zk is a console application.

1. Make a directory for zk.
2. Go to that directory.
3. Unpack all the files into that directory.
4. Run zk and follow the suggestions it gives you.

To unpack the files, use an unzip program, such as pkunzip.
No command line switches should be needed for pkunzip.  All the
files go in the one directory, and no subdirectories are created.

When you type "zk", to run zk.exe, it should display several lines
of text followed by "zk>", the zk command line prompt,  If you want
to exit from zk, the command to exit is "qq", and then you can run
it again by typing "zk" again.  Read the text it displays on the
screen to get suggestions for how to proceed from there.
