The SHARE v. 1.1 program code and input files are contained
in a tar.gz archive (filename share_ratiosv1.1.tar.gz).
To unpack it, create a SHARE directory, put the archive
in it, and execute the following commands:

gunzip  share_ratiosv1.1.tar
tar -xf  share_ratiosv1.1.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 could take hours).

The format of each file included is described in detail in the
SHARE paper, available at http://arxiv.org/abs/nucl-th/0404083

  chi2.data       Input for the SHARE Mathematica fitting package
                  (section 8 in paper)
  decays.data     The complete Particle Data Group decay tree
                  (section 3.3 in paper)
  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)
  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)
  rtonlnrm.data   Another version of the FORTRAN fit input file,
                  in which ONLY T and gamma_q are allowed to vary.
                  This "reduced fit" is sometimes useful in full
                  non-equilibrium fits, which are considerably more
                  difficult due to the presence of false minima
                  and multiparameter correlations.
  share1.1.nb     SHARE code in Mathematica
                  (section 8)
  sharerun.data   A "representative" run input file
                   (section 4)
                  It orders reading of the data from totratios.data,
                  performance of a fit with all 6 available models
                  (full equilibrium,  strangeness non-equilibrium,
                  strangeness and light quark non-equilibrium, each with
                  width and no-width), drawing chi^2 profiles and
                  calculating  extensive quantities for each model
  sharev1.1.f     SHARE v1.1 FORTRAN code.    Should contain 3872 lines.
  thermo.data     A representative thermal parameter input file
                  (section 3.1)
                  It is set to reasonable non-equilibrium fit values
  totratios.data  A representative data input file
                  (section 3.4)
                  Containing ratios drawn from current (July 2004)
                  RHIC experiments.
                  When fitting from this input file, exact strangeness conservation 
                  is assumed.
  totratext.data  A representative data file containing extensive
                  thermodynamic quantities (to be calculated)

Once the directory is unpacked, the program should be compiled with

./fortrat

After this, typing

./sharev1.1.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
