The GNU Emacs Calculator
************************
"Calc 2.02" is an advanced desk calculator and mathematical tool that
runs as part of the GNU Emacs environment.
This manual is divided into three major parts: "Getting Started," the

the major aspects of Calculator use in an easy, hands-on way. The
remainder of the manual is a complete reference to the features of the
Calculator.
For help in the Emacs Info system (which you are using to read this
file), type `?'. (You can also type `h' to run through a longer Info
tutorial.)

Version 1, February 1989

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
========
The license agreements of most software companies try to keep users
at the mercy of those companies. By contrast, our General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not
price. Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, that you receive source code or can get it if you want it,
that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of a such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must tell them their rights.
We protect your rights with two steps: (1) copyright the software,
and (2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
1. This License Agreement applies to any program or other work which
contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work
based on the Program" means either the Program or any work
containing the Program or a portion of it, either verbatim or with
modifications. Each licensee is addressed as "you".
2. You may copy and distribute verbatim copies of the Program's source
code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep
intact all the notices that refer to this General Public License
and to the absence of any warranty; and give any other recipients
of the Program a copy of this General Public License along with
the Program. You may charge a fee for the physical act of
transferring a copy.
3. You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of
Paragraph 1 above, provided that you also do the following:
* cause the modified files to carry prominent notices stating
that you changed the files and the date of any change; and
* cause the whole of any work that you distribute or publish,
that in whole or in part contains the Program or any part
thereof, either with or without modifications, to be licensed
at no charge to all third parties under the terms of this
General Public License (except that you may choose to grant
warranty protection to some or all third parties, at your
option).
* If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the simplest and most usual way, to print
or display an announcement including an appropriate copyright
notice and a notice that there is no warranty (or else,
saying that you provide a warranty) and that users may
redistribute the program under these conditions, and telling
the user how to view a copy of thi
