The SHARE v. 2.1 program code and input files are contained
in a tar.gz archive (filename sharev2.1.tar.gz).
To unpack it, create a SHARE directory, put the archive
in it, and execute the following commands:

gunzip  sharev2.1.tar
tar -xf  sharev2.1.tar

The following files will then be created, enough for a
complete "representative" run of SHARE.
It should be noted that this run explores all of the calculational
potential of SHARE, including computations incorporating particle
widths.   Some of these, highlighted in the comments in the sharerun.data 
file, are very long (chi^2 profiles with particle widths could take hours).

The format of each file included is described in detail in the
SHAREv2.x paper, available at 
http://arXiv.org/abs/nucl-th/0603026

The SHAREv1.x manual is available at 
http://arxiv.org/abs/nucl-th/0404083

List of the files:

  decays.data     The complete Particle Data Group decay tree
                  (section 3.3 in v1.x manual)
  dec_no.data     An empty decays file, useful for testing  the program
                  calculations (abundancies reduce to modified Bessel functions)
                  as well as studying the role of resonances in stable particle 
                  ratios
  fortrat         A shell script compiling (in f77) the FORTRAN code
                  which should be modified depending on location of FORTRAN
                  (g77 or f77) and CERN library of programs
  particles.data  Particle properties, with full widths
                  (section 3.2 in v1.x manual))
  partnowdt.data  Particle properties, with no widths.
                  Calculations with this input file require
                  considerably less computational time, and it
                  suffices when there are no resonances in the fit.
  ratioset.data   The FORTRAN fit input file
                  (section 3.5 in v1.x manual)
  sharerun.data   A "representative" run input file
                   (section 4 in v1.x manual)
                  including an analysis of fluctuations and yields similar to what was presented in
                  QM2005, http://arXiv.org/abs/nucl-th/0509067

  sharerun.data_onefile   The same file in the "one file" format, as explained in section 4.1 of
                   v2.x manual

  samplefit200    A directory containing the output files generated by running the provided "sharerun.data",
                  as a debugging/comparison standard

  sharev2.1.f     SHARE v2.1 FORTRAN code.    The header contains information about bug fixes
  thermo.data     A representative thermal parameter input file
                  (section 3.1  in v1.x manual)
                  It is set to reasonable non-equilibrium fit values
  totbar200.data  A representative data input file
                  (section 3.4  in v1.x manual)
                  Containing:
                  - ratios drawn from current (July 2004) RHIC experiments, http://arxiv.org/abs/nucl-ex/0403014.
                  - Published yields of the Phi, http://arXiv.org/abs/nucl-ex/0406003 and pions,
                   http://arxiv.org/abs/nucl-ex/0310004
                  - preliminary K/pi dynamical fluctuations, http://arXiv.org/abs/nucl-ex/0503023 
                  When fitting from this input file, exact strangeness conservation 
                  is assumed.

   star.feed      An example of a decay feed-down coefficients file.
                  See v2.x manual 
                  section 2

   fotrat         A shell-script that compiles sharev2.1

Note that SHARE requires CERN libraries, to be downloaded separately from
here.
The compiler statement (in file "fortrat") is
f77  -L/usr/local/cern/pro/lib -o sharev2.1.exe sharev2.1.f  -lmathlib -lkernlib -lpacklib -C
which assumes that the CERN libraries are in directory 
/usr/local/cern/pro/lib
If this is not true on your system, fortrat should be changed accordingly.  
                 
Once the directory is unpacked, the program should be compiled with

./fortrat

After this, typing

./sharev2.1.exe

should produce a correct run with a detailed output which
shows the program's capability.  
Several output files are produced, with the following names
as default.
The contents of each file are explained in detail in section 4 of the 
paper.

fit*.out     Fit output files
graph*       Fit output graphics (experiment, fitted values, calculated values)
ext*.out     Extensive quantities calculated within the various models
prof*        Chi^2 profiles and correlation functions for the various
             fits

*nwd*, *nowd*   No width, strange and light non-equilibrium
*width, *wd*    Width, strange and light non-equilibrium
*neq*           No width, full equilibrium
*weq*           Width, full equilibrium
*nweqs*         No width, strangeness non-equilibrium
*wdeqs*         Width, strangeness non-equilibrium
