The UNIX version of PREPRO2015 comes with FORTRAN
source codes, in compressed form.

1) Copy UNIX.tar.gz to your hard drive. First uncompress
   and untar. After installation you should have a directory 
   named PREPRO15 that contains all of the files you will
   need; you can delete UNIX.tar.gz 

2) This system comes with batch files to compile and
   load all of the codes. Execute the batch file
   for your type of computer, e.g., IBMPC.BAT, LINUX.BAT,
   MAC-OSX.BAT, etc. This could take between 5 and 45
   minutes to complete, depending on the speed of your
   computer. 
 
   If the codes EVALPLOT and COMPLOT fail to compile and
   load then you may need to change the path in the
   Makefile to the directory that contains your X-Windows
   routines, i.e. /usr/lib/X11

3) If all of the codes compile you should have a total of
   20 executables - 16 in the directory SOURCES, 2 in the
   directory SOURCES/COMPLOT and 2 in the directory 
   SOURCES/EVALPLOT. Copy or move all 20 executables to
   the UNIX directory - you should then have 43 files in
   your UNIX directory.

4) To VERIFY proper installation, it is recommended
   that after installation you execute VERIFY.BAT. This
   is a batch file that will run the codes in sequence.
   The final two codes will display the calculated
   cross sections (EVALPLOT), and compare the results
   you calculated to a standard set of results (COMPLOT).
   Difference of about 1 % to 2% are acceptable; larger
   differences indicate an installation problem.
 
5) If you have any problems notify the Nuclear Data
   Section, IAEA, Vienna, Austria.
