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

   1. Unpack the sources slope_rev.tar.gz : 
           gunzip slope_rev.tar.gz
           tar xvf slope_rev.tar

      This creates a directory ./slope_rev with all the necessary files:
      
         README
	 Makefile

         s_reverse.h         Headerfile slope arithmetic in reverse mode
	 s_reverse.cpp       Implementation slope arithmetic in reverse mode
	 helpfuncs.h         Headerfile utilities
	 helpfuncs.cpp       Implementation utilities
	 
	 rslope_ex1.cpp      Example: forward_sweep, reverse_sweep
	 sltestr.cpp         Example: Some functions
        
   2. Make sure you have the C-XSC 2.0 library
      
   3. Type 
           cd ./slope_rev

   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_rev.a  and
      the example programs.  

Executable files:
=================
   -  rslope_ex1 
   -  sltestr

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_rev.a and libcxsc.a:

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

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

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

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