The LINUX version of PREPRO2023 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 - all of the files in the LINUX packages (32 or 64 bit)
base directory are in UNIX format, ready to be used by any LINUX system.

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 directory named LINUX32 or
   LINUX64, that contains 49 and a directory named SOURCES; 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-LINUX.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 SOURCES sub-directory.

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 SOURCES sub-directory and use the LINUX.mak 
   as a makefile.

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