rCalc                                    http://rcalc.sourceforge.net/
======================================================================

rCalc is a symbolic calculator for GNOME, featuring: 

      Standard infix expressions - you type something like 1+3*sin(pi) and
	it will be evaluated for you in the correct order. 
      Variables (this is where the `symbolic' comes in). If you enter an
	expression like a=1+e^2.5, then the result is stored in a variable
	called a. You can then use it in future expressions, like
	b=sqrt(a*5). 
      Furthermore, variables are stored between sessions unless you
	delete them. 

     rCalc is therefore not like other calculator programs, such as xcalc,
kcalc or gcalc. It currently supports simple functions such as /, *, +, -
and ^ ('raise to the power of'), as well as more complex ones like the
trigonometric functions (sin, cos, tan, asin, acos and atan), the
hyperbolic functions (sinh, cosh, tanh, asinh, acosh and atanh), sqrt,
log, ln, abs and int. It also has two built-in constants, pi and e.


Installation
------------

     To install rCalc on your system you need GNOME installed, and of
course all the things that GNOME needs. See http://www.gnome.org/ for
details about that.

Once you have untarred the sources, cd into the directory and type:

	./configure --prefix=`gnome-config --prefix`
	make
	su
	make install

Note the non-standard ./configure line: without the --prefix= option,
the help files will be installed in the wrong place and you will have no
online help! 

Then, you can type 'rcalc' anywhere and it will run. If you get fed up of 
it, then you can remove it by typing:

	su
	make uninstall

from the directory containing the source.

     The file INSTALL contains generic instructions for using the
configure script, or you can type ./configure --help to see a list of
options. Please note the --prefix option stuff above.


Usage
-----

     Look in the help menu =).
