Installation:
=============

   1. Unpack the sources slope_for.tar.gz : 
           gunzip slope_for.tar.gz
           tar -xvf slope_for.tar

      This creates a directory ./slope_for with all the necessary files:
      
         README
	 Makefile
      
         slope_ari.h         Global headerfile
	 slope.h             Headerfile onedim. slope arithmetic
	 slope.cpp           Implementation onedim. slope arithmetic
	 multi_dim_slope.h   Headerfile multidim. slope arithmetic
	 multi_dim_slope.cpp Implementation multidim. slope arithmetic
	 helpfuncs.h         Headerfile utilities
	 helpfuncs.cpp       Implementation utilities
	 
	 prog1.cpp           Example: One-/multidim. slope arithmetic
	 prog2.cpp           Example: Use of function fseval
	 sltestv.cpp         Example: Some functions
	 nlg.cpp             Example: Nonlinear equations
	 nlgsrump.cpp        Example: Nonlinear systems of equations with
	                              an example from S. Rump	    
        
   2. Make sure you have the C-XSC 2.0 library
    
   3. Type 
           cd ./slope_for
  
   4. Edit the file Makefile and set the correct path to your 
      installation of the C-XSC 2.0 library

   5. Compile the sources using  make:
           make all    
      This creates the library  libslope_ari.a  and
      the example programs.  

Executable files:
=================
   -   nlg
   -   nlgsrump
   -   prog1
   -   prog2
   -   sltestv

Clean directory:
================
To delete the executable and the object-files type 
       make clean
 
Using the slope arithmetic:
===========================
When you compile and link code using slope arithmetic and C-XSC routines, 
you have to define an include path and a library path and you have to link 
the libraries libslope_ari.a and libcxsc.a:

  g++ -I<incl1> -I<incl2> -L<lib1> -L<lib2> prog.cpp -lslope_ari -lcxsc -o prog

Meaning of <...>:
Include-paths: <incl1>  <cxsc directory>/include
               <incl2>  <slope_for directoy>

Library-paths: <lib1>   <cxsc directory>/lib
               <lib2>   = <incl2>

Note, that -I<incl1> and -L<lib1> are not necessary, if you have set the path
variables.
