############################################################################
# \PURPOSE
#    To create nice postscript figures out of a gnuplot plot
#
# \USAGE
#    from the command line in gnuplot, execute the command
#         call 'gnuplot2ps-fig.plt' 'filename' 
#
# \DATE
#    03 Jun 2005

# \AUTHOR
#    Simone Zuccher
#
# \PHILOSOPHY
#    First set the correct paramenter in gnuplot and then export the figure
#    in pslatex format. By running LaTeX on a LaTeX file properly created
#    a ps file is obtained, then the BoundingBox is set to the correct
#    paramenters.
#
# \INPUT(S)
#    The name of the output file, filename
#
# \OUTPUT(S)
#    filename.ps
