This is a relocatable version of yorick. The yorick and gist
executables are in the bin/ subdirectory. You can name this directory
whatever you want in order to place it in your file system; a typical
location might be /usr/lib/yorick/1.6.
You cannot move either yorick or gist relative to the other files in
this directory; yorick and gist find the files they need by moving
relative to the executable. However, you may place a softlink from
another directory to point to bin/yorick or bin/gist. For example,
ln -sf /usr/lib/yorick/1.6/bin/yorick /usr/bin/yorick
puts a softlink in /usr/bin (which is probably on your PATH), so that
you can just type "yorick" to start yorick.
Yorick is a command line program. If you have the X Window System
version of emacs, you will probably prefer to run yorick from emacs.
Read the file yorick.el in this directory to learn how to do that. In
a nutshell, you put a line like
(load "/usr/lib/yorick/1.6/yorick" nil t)
in your ~/.emacs file, then type M-x yorick RET to emacs. That will
give you nice command line recall and editing, as well as a text
editor for yorick source that understands yorick syntax.
(Gist is a CGM browser. If you don't know what that means, forget it.)
Look in the doc/ subdirectory for documentation on how to use yorick.
The interpreted library in the i/ directory contains many yorick
programming examples, including the demoX.i instructional programs.
