The IBM/LINUX version of PREPRO2012 comes with executable codes, in 
compressed form, for 32 and 64 bit LINUX systems; choose the one that is
appropriate for your system, either LINUX32 or LINUX64.  

1) Copy either LINUX32.tar.gz or LINUX64.tar.gz to your hard drive. First uncompress
     and untar it. After installation you should have a single directory named PREPRO12
     that contains 42 files; you can then  delete LINUX32.tar.gz or LINUX64.tar.gz.

2) 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.

3) 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.

   If plots are displayed before the batch file (VERIFY.BAT) finished, the entire
   system has been verified and is ready to use. If you do not obtain plots, there
   was an ERROR during installation; in this case 5) below.

   If the codes EVALPLOT and COMPLOT fail to execute then you may need to 
   recompile them and change the path in the Makefile (LINUX.MAK) to the directory 
   that contains your X-Windows routines. i.e. /usr/lib/X11. In this case you will need
   the FORTRAN source codes that are contained in the UNIX distribution.

4) LINUX systems now vary from one type of computer to another, so that the LINUX 
    executables included in this package may not run on your computer. In this case you 
    MUST re-compile the codes; start from the UNIX package that icludes source codes 
    and use the LINUX.mak as a makefile.

5) If you have any problems notify the Nuclear Data Section, IAEA, Vienna, Austria.
