I'm announcing the availability of my own implementation of rc, the
AT&T plan 9 and Unix v10 shell in use at Bell Labs.

I'm releasing "version 0.9", which means that rc has seen a lot of
testing by a few people, but that now it's time to freeze any
development completely and let a larger number of users shake the
remaining bugs out. When this happens, I will (with hope, in the near
future) release "version 1.0".

What is rc?

	rc is a small shell, similar to the Bourne shell. It has
	powerful variable manipulation primitives, however, which makes
	it a very useful shell language. It is *not* another
	bash/ksh/tcsh which tries to do everything but fetch your
	slippers. You can use it interactively (as I have been doing
	for the last several months) or you can use it to write
	fast-starting and easy-to-read shell scripts; rc's syntax is
	based on C, much more so than the so-called C-shell.

Where can I get rc?

	The shell is available by anonymous ftp from archone.tamu.edu,
	in ~ftp/pub/rc. I also honor personal email requests for an
	email copy.

How do I find out more about rc?

	I've enclosed here an introduction to rc which comes with the
	rc source distribution. It is an outline of its main features;
	some experience with Unix shells is assumed.

	You can also read about AT&T's rc in the Unix Research 10th
	edition manuals. These are available in bookstores in two
	volumes, published by Saunders College Publishing.

Enjoy.

Byron Rakitzis.
